+19961124 change: forced res_query() return value to fit inside incoming
+ buffer size. allegedly there are buggy versions of res_query()
+ that don't guarantee this.
+19961122 qmail 0.93, gamma.
+19961122 change: allowed empty arg list in forward.
+19961121 change: qmail-smtpd now uses unknown (like qmail-qmtpd) rather
+ than dying if environment variables are not set.
+19961121 cleanup: reorganized helo handling in qmail-smtpd.c.
+19961121 cleanup: eliminated newfield_rec.
+19961121 cleanup: introduced DATE822FMT. used it in received.c.

+ tnx LW.
+19961117 change: qmail-start sets logger gid to GID_NOFILES.
+19961117 bug: ipme_init() uses a fixed-length buffer for SIOCGIFCONF.
+ impact: qmail-smtpd and qmail-remote will die if there are too
+ many local IP addresses. tnx MD. fix: ipme_init() now
+ dynamically allocates space, up to 200000 bytes, as long as
+ SIOCGIFCONF keeps failing. note that this is a very widespread
+ bug; it's in amd, exim, mrouted, named, nntpd, rarpd, sendmail,
+ tcpdump, timed, xntpd, and probably dozens more programs.
+19961117 portability problem: on BSD 4.4 and various other systems,
+ SIOCGIFCONF will truncate long lists and return success.
+ impact: on those systems, qmail-smtpd and qmail-remote will
+ miss some local IP addresses if there are too many. fix:
+ ipme_init() now checks whether there is enough space left in
+ the buffer for another ifreq, plus 64 bytes JIC. yuck.
+19961117 change: ipmeprint now flushes only at end.
+19961117 cleanup: introduced subfdinsmall. used it in qmail-clean.c,

+19961116 change: rewrote qmail-showctl more professionally.
+19961115 change: added several tests to this will
+ affect many systypes.
+19961115 change: qmail-alias now treats most exit codes as soft errors.
+19961115 change: revamped exit codes everywhere for 0, 100, 111.
+19961114 change: added splogger.
+19961114 portability problem: Sun's cc recognizes sqrt() as a builtin,
+ even if math.h is not included and sqrt is defined statically.
+ yuck. impact: when qmail is compiled with Sun's cc, next-retry
+ times are all screwed up. tnx PJG. fix: my sqrt() is now called
+ squareroot().
+19961114 change: dns_ip() now recognizes []. tnx DS.

+19961012 portability problem: under HP-UX 9, can't setgroups() to 65537.
+ impact: couldn't compile under HP-UX 9. fix: use 0 instead of
+ 65537 in chkshsgr.c. tnx HHO.
+19961008 change: added several qlx codes.
+19961008 cleanup: eliminated qlx from qmail-alias.

+19961003 bug: if ipme_init() returned -1, qmail-remote would continue,
+ blindly assuming that all addresses are local. impact: on
+ systems with too many aliases, all remote deliveries fail. tnx
+ MD. fix: qmail-remote now dies with temp_oserr() on any result
+ other than 1.
+19961003 portability problem: all pre-4.9.4 versions of bind barf,
+ badly, on CNAME queries to lame servers. what a crappy system.
+ even if the resolver doesn't barf, the next name server down
+ the line may barf. impact: qmail can't get mail through to
+ domains that are (1) lame and (2) running old versions of bind.
+ fix: never, ever, do a CNAME query. dns_cname() now does an ANY
+ query instead. this, like sendmail's analogous procedure, is
+ unreliable when a CNAME is mixed with other records.
+19961001 cleanup: switched to libfd in qmail-start.c.
+19960929 cleanup: renamed auto-hasmkffo.h to hasmkffo.h.

+ holes, four'' -> ``ten most recent sendmail security holes,
+ five.''
+19960926 change: added tcpcontrol notes to FAQ.
+19960926 change: qmail-smtpd now immediately closes connection, with a
+ warning message dedicated to Solaris, if stray newlines show up
+ in the incoming data.
+19960926 change: added INSTALL.boot.
+19960926 portability problem: on systems that can handle IP interface
+ aliases (i.e., on sa_len systems), SIOCGIFADDR returns the
+ primary address for an alias. impact: ipme_init() did not
+ include alias addresses. fix: ipme_init() avoids SIOCGIFADDR on
+ sa_len systems; on these systems, the address we want is
+ already in ifr. tnx DM.
+19960926 change: qmail-alias kills itself if locking takes longer than
+ 30 seconds.
+19960926 change: qmail-pop3d no longer moves messages. tnx RS.

+ holes, three'' -> ``nine most recent sendmail security holes,
+ four.''

+ control signals under more systems than HP-UX. impact: on some
+ systems (e.g., Solaris), qmail daemons would be killed. fix:
+ INSTALL now tells everybody to use csh -cf.
+19960920 change: added queue-run section to FAQ.
+19960920 change: in pine-crashing question in FAQ, added -oem and -oi,
+ so that change will work with the real sendmail too.
+19960919 change: added CNAME section to FAQ. tnx to various people.
+19960919 change: eliminated QQX_EXECHARD and QQT_EXECHARD. this means
+ that all qmail-queue invocation failures are now soft, even
+ things like EPERM.
+19960919 change: replaced ``No such address'' with ``Sorry, no mailbox
+ here by that name.'' tnx G2A.
+19960919 change: qmail-remote now includes host name in no-such-host
+ messages. tnx G2A.
+19960919 change: replaced ``Temporarily unable to canonicalize address''
+ with ``CNAME lookup failed temporarily.''

+19960915 change: added qsutil error messages to qmail-log.5.
+19960915 change: qsutil error messages are now alerts.
+19960915 portability problem: on some systems, logger appears to use
+ syslog(pri,buf) instead of syslog(pri,"%s",buf). tnx JC.
+ impact: logger could barf or crash if fed messages containing
+ %. an attacker could easily cause a crash, eliminating qmail's
+ logs. fix: % is no longer considered safe for logs.
+19960912 cleanup: split seek.c into seek_*.c.
+19960912 cleanup: replaced seek_to() with seek_set().
+19960912 cleanup: introduced libseek.a.

+19960825 change: added LINELEN macro to qmail-inject for unparse.
+19960825 change: token822_unparse now takes linelen argument. (leaving
+ two spaces on the right before linelen.)
+19960824 cleanup: renamed token as token822.
+19960822 portability problem: under NEWS-OS, /bin/mail and /usr/ucb/mail
+ invoke sendmail with -E and -J options. tnx TU. impact:
+ couldn't send mail with those programs. fix: accept opts,
+ including _optional_ args. ugh.
+19960821 change: sendmail now quits if invoked as newaliases. tnx TU.
+19960821 portability problem: under NEWS-OS, dirent.h needs sys/types.h.

+ possible future getpwnam() replacements.
+19960731 change: popped subfderr buffer up to 32 characters. made sure
+ that everybody flushed subfderr as necessary.
+19960731 change: maildir2qmtp now prints filenames and responses.
+19960731 change: maildir2smtp now prints filenames it's trying and
+ relevant portion of SMTP responses.
+19960731 change: used succwrite() in maildir2smtp, maildir2qmtp.
+ simplifies code quite a bit.
+19960731 change: qmail-remote's blast() checks sooner for write errors.
+19960731 change: added better -e option to sendmail. tnx TG.
+19960731 change: added maildir2qmtp.
+19960730 cleanup: eliminated die_nomem() in maildir2smtp.c.
+19960730 change: dns_cname now pretends that "foo." is a CNAME for "foo"
+ to give the desired behavior for people who misuse DNS and
+ violate RFC 822. tnx RN.
+19960730 change: dns_cname now tests for empty names and ] on every
+ loop.
+19960730 change: used LSPAWN_BREAK in qmail-send.c for usermap.
+19960730 change: updated header example in qmail-header.5.
+19960730 change: added printbreak. auto-configured BREAK in dot-qmail.5,
+ qmail-lspawn.7, qmail-send.8, qmail-upgrade.7, qlist2.
+19960730 change: added printnumd. auto-configured NUMD in qmail-send.8,
+ qmail-limits.8.
+19960730 change: added printsplit. auto-configured split in qmail-upq.
+19960730 change: added dot-qmail.5.
+19960730 change: qmail-smtpd now treats HELO as including RSET.
+19960730 change: added moreinfo to qlist usage message.
+19960729 change: improved an error message in qmail-alias.
+19960729 cleanup: merged qmeox(), qmeodx().
+19960729 bug: failure to stat .qmail-owner was not an error. impact: if
+ stat failed temporarily (e.g., because of NFS), .qmail-owner
+ would be incorrectly ignored, so outgoing message would have
+ wrong envelope sender. fix: qmail-alias does temp_nfsqmail() if
+ stat() returns a temporary error.
+19960729 change: added RFCOWNER.
+19960729 change: added qmtpd setup question to FAQ.
+19960729 change: added qmail-qmtpd.
+19960728 change: revamped maildir2smtp error messages.
+19960728 change: revamped maildirwatch error messages.
+19960728 change: revamped maildir2mbox error messages.
+19960728 change: used strerr in maildir_scan().
+19960728 change: used strerr in maildir_chdir().
+19960728 change: introduced strerr.
+19960728 bug: the new tcp-env tried to read from an ndelay socket.
+ impact: TCPREMOTEINFO would always be empty. fix: unset ndelay
+ in remoteinfo.c.
+19960728 bug: if maildir2smtp saw a permanent failure after MAIL, it
+ failed to do RSET. impact: all further messages would be
+ rejected at the MAIL stage. fix: maildir2smtp now always does
+ RSET. tnx JW.
+19960728 cleanup: qmail-alias now applies lowercase and dot-to-colon
+ conversion directly to dashext, leaving everything else alone.
+ this works since all .qmail access is factored through dashext.
+19960727 portability problem: under NeXTStep, -posix is almost entirely
+ broken. impact: qmail daemons would dump core under NeXTStep.
+ fix: turn off -posix, except for loading qmail-setup, which
+ needs mkfifo(); NeXT, bless them, didn't put mkfifo() into the
+ C library where it belongs. this requires a new make command,
+ namely loadfifo.
+19960727 change: all characters 33-126 are now considered safe for logs.
+ tnx MD.
+19960727 cleanup: eliminated qp variable from mailforward().
+19960727 cleanup: maildirwatch.c includes headerbody.h.
+19960727 cleanup: eliminated match from maildirwatch.c.
+19960727 cleanup: eliminated code variable from maildir2smtp.c:doit().

+19960727 cleanup: spawn.c now declares initialize().
+19960727 cleanup: qmail-lspawn.c now includes str.h, byte.h.
+19960727 cleanup: qmail-inject.c now includes quote.h.
+19960727 change: qmail-check now checks separately for group
+ readability and other readability.
+19960727 bug: maildir2smtp didn't check flagehlo in PIPELINING parsing.
+ impact: a server that said PIPELINING at any point, not just
+ EHLO, would receive pipelined data. fix: check flagehlo.
+19960727 bug: readsubdir was calling pause(). impact: if a subdirectory
+ was removed, qmail-send would hang. fix: use rs->pause().
+19960727 change: used error_str in qmail-qread.
+19960727 change: qmail-qread now looks for local/remote open errors.
+19960727 cleanup: added warn() in qmail-qread.c.
+19960727 change: qmail-qread now exits 111 for temporary errors.
+19960727 change: used error_str in qmail-setup.

+19960727 change: added check target to Makefile.
+19960727 change: replaced qmail-setup with make setup in INSTALL.
+19960727 change: indirected fake targets through do- targets.
+19960727 change: added setup target to Makefile.
+19960727 change: qmail-makectl now makes sure that defaultdomain has
+ at least one dot. e.g., ->, not com.
+19960726 bug: quote() failed to quote commas. impact: addresses
+ containing commas would not have been quoted correctly for
+ Return-Path or for SMTP MAIL FROM. fix: quote commas.
+19960726 change: sendmail now mentions qmail-qread, not qmail-mailq.
+19960726 change: qmail-alias now expects ext arg. this eliminates
+ LSPAWN_BREAK from qmail-alias and gives lspawn almost complete
+ control over the local -> ~user/.qmail-ext transformation. the
+ exception is that qmail-alias always uses ~user/.qmail,
+ ignoring ext, if local is the same as user.
+19960726 change: qmail-lspawn passes ext to qmail-alias.
+19960726 change: alloc() now uses up a 4K space before calling malloc().
+19960726 change: ipalloc allocation base is now 10. 100 was silly.
+19960726 change: stralloc allocation base is now 30.
+19960726 change: injectbounce() now supports the owner hack.
+19960726 change: qmail-smtpd no longer requires HELO. tnx K1J.
+19960726 cleanup: replaced makereceived() with dohelo().
+19960726 change: qmail-smtpd is back to 555 for syntax errors.
+19960725 change: qmail-alias now supports the owner hack. tnx to RN for
+ prodding me to look at this problem.
+19960725 change: senderadd() now supports the owner hack.
+19960725 cleanup: split off senderadd().
+19960725 change: added pine-crashing note to FAQ.
+19960725 change: added procmail config.h note to INSTALL.mbox.
+19960725 change: added elm TMPDIR note to INSTALL.mbox.
+19960725 change: added pine.conf note to INSTALL.mbox.
+19960724 change: added fixup note to FAQ.
+19960724 change: qmail-inject now exits 111 for temporary errors.
+19960724 change: qmail-smtpd now appends RELAYCLIENT to incoming
+ recipient domain names.
+19960724 cleanup: moved relayclient out of qmail-smtpd's addrallowed()
+ into caller.
+19960724 change: added rcpthosts wildcards.
+19960724 change: added clean target to Makefile.
+19960723 change: added virtualdomains exceptions.

+19960722 change: incorporated relaymap, contributed by LW. renamed it
+ as smtproutes.
+19960722 change: qmail-popup now supports APOP. suggested by BG, who
+ distributed similar changes.
+19960722 change: qmail-popup now sends APOP timestamp to checkpassword.
+19960722 cleanup: in qmail-popup, split off doanddie().
+19960722 change: qmail-popup now prints APOP timestamp in banner.
+19960722 change: added hostname argument to qmail-popup.
+19960722 cleanup: in qmail-popup, split out() into out(), outflush().
+19960722 cleanup: in qmail-popup, introduced pop3_greet().
+19960721 portability problem: under Unisys SVR4, hostname is not in the
+ usual path. impact: qmail-makectl fails. fix: added hostname
+ command here, used it in qmail-makectl.
+19960721 portability problem: on some sysctl-based systems, apparently
+ gethostname() doesn't write anything if the output buffer is
+ too small. it should write a truncated name. impact: if anyone
+ has a hostname longer than 64 characters, maildirs could get up
+ to 64 characters of garbage, rather than a truncated hostname.
+ fix: qmail-alias now does *host = 0 before calling gethostname.
+19960721 change: updated FAQ examples from qsmhook to preline.
+19960721 change: added preline.
+19960721 change: qsmhook now uses signal_init, signal_uninit.

+ for unparseable header fields.
+19960720 change: logo is now dolphin. tnx CEJ.
+19960719 qmail 0.76, beta.
+19960719 change: used LSPAWN_BREAK in qmail-alias for deciding how to
+ handle extensions. this should produce better behavior in the
+ (unsupported) case that LSPAWN_BREAK is not a hyphen.
+19960719 bug: qmail-smtpd didn't check for null arg on MAIL, RCPT.
+ impact: qmail-smtpd would deref 0 and crash. fix: qmail-smtpd
+ now gives syntax error on null arg.
+19960719 change: documented UFLINE in qmail-command.8. tnx TG.
+19960718 change: added maildir2smtp.
+19960718 cleanup: introduced maildir.c. used it in maildir2mbox.c,
+ maildirwatch.c.
+19960718 change: added maildirwatch.
+19960718 cleanup: maildir2mbox now sets up pq2 as it is deleting from
+ pq, rather than simultaneously with pq.
+19960718 change: added H_DELIVEREDTO.
+19960718 portability problem: Unisys requires -lsocket -lnsl. impact:
+ couldn't compile under Unisys. fix: added unix_sv section to
+ tnx TVP.
+19960718 change: added unix_sv section in find-systype. tnx TVP.
+19960717 change: qmail-alias now appends newline if .qmail does not end
+ with a newline. tnx MC.
+19960717 change: qmail-alias now defers delivery for a blank line only
+ if it is the first line of the file. handles user behavior
+ described by MC of putting many newlines at end of file.
+19960717 bug: qmail-inject looked for dots in user part, not just host
+ part, when deciding whether to use defaultdomain. impact: the
+ address joe.bloggs@here didn't have defaultdomain added. fix:
+ qmail-inject now stops at the @.
+19960717 change: updated INSTALL.alias to mention qmsmac.
+19960717 change: syntax error code for SMTP is now 501.
+19960717 change: added -e option to sendmail. tnx TG.
+19960716 change: changed ~alias files to .qmail-local, not .qmaillocal.
+ suggested by many people.
+19960716 change: redid qmail-alias/qmail-lspawn interface.
+19960716 change: replaced EXTENSION, USEREXT with LOCAL.

+19960704 change: qmail-upgrade.7 now warns administrators that ~alias
+ generally doesn't apply to addresses starting with a user name.
+19960703 change: added echo \c note to FAQ. tnx PJG.
+19960702 change: qmail-smtpd now accepts HELO without an argument.
+ tnx K1J, J1B.
+19960627 change: qmail-lspawn.8 now mentions that qmail-lspawn doesn't
+ set up supplementary groups. tnx TG.
+19960625 portability problem: under Linux, read(,,0) doesn't do proper
+ error slippage. impact: timeoutconn() would always report
+ success; if a connection failed, qmail-remote would report a
+ greeting failure and skip all further MX records. tnx ME. fix:
+ timeoutconn() now uses getpeername() to check for success.
+19960625 change: qmail-smtpd now mentions disk full for QQT_WRITE.
+19960625 change: qmail-inject now mentions disk full for QQT_WRITE.
+19960622 change: if RELAYCLIENT is set, qmail-smtpd skips rcpthosts.

+19960605 portability problem: under Solaris, /usr/bin/groups incorrectly
+ reports your groups in /etc/group, rather than the results of
+ getgroups(). tnx MD, PJG. impact: test #19 in INSTALL fails.
+ fix: added special note to test #19 (sigh) about Solaris.
+19960605 change: improved maildir setup commands in INSTALL.mbox.
+19960605 change: on success, qmail-alias logs forwarding qp. 9 lines
+ extra code.
+19960605 change: qmail-send logs qp for bounce. 6 lines extra code.
+19960605 change: qmail-smtpd includes qp in its response when it accepts
+ a message. 7 lines extra code. requested by MD and others.

+19960525 change: added qmail-popup. tnx RN.
+19960525 change: added elm filter section to FAQ. tnx GB.
+19960502 portability problem: on many systems, select() on an
+ almost-full pipe incorrectly says writable. tnx ME for running
+ into this and helping track it down. impact: if qmail-send
+ writes a pipeful to qmail-lspawn or qmail-rspawn before they
+ can react (because of high concurrency, high load, or long
+ addresses), it will receive an incorrect -1/EAGAIN, and will
+ conclude that spawn died. sysadmin will have to restart qmail,
+ and messages will be duplicated. fix: in qmail-send.c,
+ busy-loop if write() to spawn returns any error other than
+19960501 bug: qmail-alias treated NAMETOOLONG and NOTDIR as temporary
+ errors. impact: qmail-alias never looked for -default; even if
+ mail was destined to bounce, it would have to time out first.
+ fix: qmail-alias now uses error_temp().
+19960430 bug: qmail-smtpd treated qq crash as permanent error. impact:
+ if somebody actively kills qq, mail will be incorrectly
+ bounced. tnx SS. fix: qmail-smtpd now treats only TOOLONG and
+ EXECHARD as permanent errors.
+19960430 cleanup: eliminated QQT_TTY from qqtalk.h.

+19960428 cleanup: switched to auto-generated Makefile.
+19960428 cleanup: switched to auto-generated .o dependencies.
+19960428 cleanup: eliminated fmt.o, scan.o from Makefile.
+19960428 portability problem: under HP-UX 10, the rc pgrp is sent HUP
+ when rc finishes. tnx BG. impact: the qmail daemons are killed
+ when rc finishes. fix: added special note in INSTALL (sigh) to
+ use csh -cf.
+19960427 cleanup: added PORT_SMTP in qmail-remote.c.
+19960427 cleanup: introduced timeoutwrite.c. used it in qmail-remote.c.

+ first line of a header field doesn't pass hfield_valid. tnx TG.
+19960427 change: headerbody now prepends MBOX-Line: to any header line
+ starting From_. this lets qmail-inject work with elm's bounce.
+ tnx OR, K1J, et al.
+19960426 change: added moreinfo arg to qlist and qlist2.
+19960426 change: added signal_uncatchchild() to qmail-send.c. tnx BG.
+ now, if sysadmin sets SIGCHLD to SIG_IGN before invoking
+ qmail-send [sigh], qmail-send won't screw up bounce messages.
+19960426 change: dns_cname now checks whether last character is ],
+ rather than whether first character is [, for quick return.
+19960426 cleanup: glue is now global in dns.c.
+19960426 cleanup: qmail-remote no longer does stralloc_0 for host and
+ canonhost.
+19960426 change: dns_mxip no longer rejects [foo].bar.

+ be 0-terminated.
+19960426 change: qmail-start can now take logger as an argument.
+19960426 change: qmail-start now invokes qmail-send in foreground (as
+ parent of other processes).
+19960426 change: added mailsubj. tnx GAW.
+19960426 portability problem: under some systems, can't lock read-only
+ file. impact: maildir2mbox would always fail on those systems.

+19960426 cleanup: removed unnecessary #!/bin/sh and # AUTO from
+19960426 change: added qmail-qstat.
+19960426 change: added qmail-qread.8.
+19960426 change: renamed qmail-mailq as qmail-qread.
+19960419 change: qmail-alias now defers delivery rather than skipping
+ blank lines in .qmail.
+19960419 change: in qmail-lspawn.c, lowercased name before getpwnam().
+ really getpwnam() should do this, but oh well.
+19960419 change: added username to qmail-lspawn.c, with LSPAWN_USERLEN
+ in conf-unusual.h. names longer than LSPAWN_USERLEN will skip
+ getpwnam().

+ meant to subscribe.
+19960419 change: reorganized qlist acknowledgment format.
+19960415 change: reorganized and rewrote FAQ.
+19960415 change: renamed HOWTO as FAQ.
+19960414 change: in qmail-alias, converted extension to lowercase just
+ before qmeopen(), qmeox() calls. thus EXTENSION and USEREXT and
+ RECIPIENT will preserve case passed by qmail-lspawn, while
+ .qmailext lookups will not.
+19960414 change: removed case_lowers(r) from qmail-lspawn.c. tnx JLH.
+19960414 change: moved extension . -> : conversion to just before
+ qmeopen(), qmeox() calls in qmail-alias.c. thus EXTENSION and
+ USEREXT and RECIPIENT will preserve dots.
+19960414 change: qsmhook -x now does case-independent comparison.
+19960413 change: added procmail instructions to HOWTO.
+19960409 bug: qmail-alias does not check for newlines when it generates
+ Return-Path. impact: resulting Return-Path header field will be
+ illegal, if sender address contains newline followed by
+ something other than whitespace. fix: qmail-alias now replaces
+ newline with underscore in rpline.
+19960409 change: added leaf UUCP description to HOWTO. tnx J2K.
+19960409 change: added -B option to sendmail. tnx OR.

+19960409 change: added PIPELINING declaration to qmail-smtpd. tnx JGM.
+19960409 change: qmail-smtpd now flushes output instantly after DATA,
+ QUIT, HELO, EHLO, NOOP, VRFY, or any 502.
+19960409 change: qmail-smtpd now flushes output upon read() and death.

+19960409 bug: qmail-alias produced aliasfoo-owner rather than foo-owner
+ as envelope sender for ~alias/.qmailfoo. tnx DS. impact: wrong
+ envelope sender whenever ~alias/.qmailfoo-owner existed. fix:
+ qmail-alias now checks for hyphen at beginning of extension.
+19960409 change: added _ESMTP to end of 220. tnx JLH.
+19960409 change: moved out("\r\n") out of smtp_greet() into callers.
+ this improves the flushing behavior on 221.
+19960328 qmail 0.74, beta.
+19960326 change: changed subdirectory split from 32 to 23.

+ uses of strnum.
+19960325 cleanup: in qmail-send.c, getinfo() now takes id argument.
+19960325 cleanup: qmail-send.c now preallocates space for fn, fn2.
+19960325 change: time zone is now -0000 instead of +0000. encouraging
+ DRUMS to use this as an i-don't-know-the-local-time indicator.
+19960324 change: qmail-rspawn.c now calls tcpto_clean().
+19960324 cleanup: spawn.c now calls initialize().
+19960324 change: qmail-setup makes lock/tcpto; qmail-check checks it.
+19960324 change: qmail-remote now quickly skips connect() to a host that
+ seems to be down. tnx BP for pressuring me to get this done.
+19960323 change: in qmail-alias.8, renamed mboxg as mboxrd. tnx RD.
+ idea was popularized by RD in June 1995.
+19960322 cleanup: eliminated subfd_init().
+19960322 change: qbiff now removes the word Subject.
+19960322 change: now /bin/true instead of /dev/null in the generic
+ INSTALL.ids instructions. tnx JPR.
+19960322 change: added hfield_skipname(). tnx RN.
+19960322 bug: qmail-inject did not check whether USER needed quoting.
+ impact: if USER had weird characters, the From address would
+ generally be wrong, unless the user manually set up MAILUSER
+ with proper quoting. fix: qmail-inject sets up a quoted-string
+ if necessary.
+19960322 cleanup: separated out quote_need() in quote.c.
+19960322 cleanup: added stralloc_catb.c. used it in qmail-alias.c,
+ qmail-send.c.
+19960322 change: qmail-send now uses a quadratic retry schedule from
+ birth of each message. this also eliminates clustering.
+19960322 cleanup: separated out nextretry() in qmail-send.c.
+19960322 change: qmail-remote now passes all non-@ addresses through
+ without comment, not just <> and <#>.
+19960322 change: replaced # test with anything@[] test in qmail-inject.
+19960322 change: replaced # with #@[] in qlist.c, qmail-alias.c,
+ qmail-send.c, qreceipt.c.
+19960322 change: qmail-lspawn no longer discards messages to <#>.
+19960322 cleanup: in qlist, used str_diff for <> and <#> tests.
+19960322 change: qmail-alias is now back to testing envelope sender for
+ <> and <#>, rather than things without an @.
+19960321 change: added 8BITMIME support to qmail-smtpd.
+19960321 change: added ESMTP support to qmail-smtpd.
+19960318 change: used NEWSENDER in place of SENDER for |forward.
+19960318 change: added NEWSENDER.
+19960318 change: added HCMSSC support to qmail-alias.c.
+19960318 change: added HCMSSC support to spawn.c.
+19960318 change: added HCMSSC support to qmail-remote.c.
+19960318 change: added HCMSSC support to qmail-smtpd.c.
+19960317 portability problem: SCO requires -lsocket -lnsl. impact:
+ couldn't compile under SCO. fix: added SCO section in
+ tnx JPR. note that this is for OSR 5; 3.2v4.2
+ will need more fixes, and old 3.2 is basically hopeless.
+19960317 bug: newfield_datemake would leave newfield_date alone if it
+ was already initialized, even though qmail-send calls
+ newfield_datemake anew for each bounce. impact: bounce messages
+ would usually have an incorrect Date field. fix: redid
+ newfield_datemake to update newfield_date each time.
+19960317 change: allowed . and @ in 822 phrases; 822 doesn't allow them,
+ but they do show up. tnx to the DRUMS group.
+19960317 change: replaced GMT with +0000 in date822fmt.c. this confuses
+ a few versions of getdate(), but the DRUMS group is going to
+ outlaw GMT, not just recommend against it as in 1123.
+19960317 change: redefined ALIAS_EMPTY to take advantage of . for file
+ deliveries. tnx RN.
+19960317 change: qmail-alias now allows . as well as / to start file
+ deliveries. tnx RN.
+19960317 change: qmail-alias now dies (soft) if .qmail is writable to
+ others, rather than silently ignoring it.
+19960317 change: qmail-alias now dies (soft) if flagforwardonly is
+ violated, rather than silently ignoring the bad instructions.
+19960317 change: qmail-alias now ignores x bit on empty .qmail files.
+19960317 bug: if RCPT gave 4xx and DATA gave 5xx, qmail-rspawn would
+ incorrectly assign a permanent failure to that recipient.
+ impact: in that case, mail would be incorrectly bounced. fix:
+ remove orr > 0 test from qmail-rspawn.c.
+19960310 change: tcp-env now uses signal_uninit(). [sigh]
+19960310 change: tcp-env now specifically unsets HOST and INFO if they
+ are not applicable. just trying to make it more widely usable.
+19960310 cleanup: used byte_* in remoteinfo.c, ipme.c, tcp-env.c.
+19960310 cleanup: added readwrite.h, eliminated sys.h.
+19960310 cleanup: included byte.h in qmail-send.c.
+19960310 cleanup: eliminated i and j from forward.c's main().
+19960310 cleanup: eliminated wstat from qlist.c.
+19960310 cleanup: eliminated die_nomem() parameter in qmail-setup.c.
+19960310 cleanup: eliminated i from qmail-remote's addrmangle().
+19960310 cleanup: added exit.h.
+19960310 cleanup: split ipalloc.c off of ip.c.
+19960310 cleanup: added fmt_strn.c, eliminated fmt_strncpy.c.
+19960310 change: reorganized INSTALL to do some pre-upgrade tests.
+ tnx RN.
+19960310 change: reordered steps in upgrade procedure in INSTALL.
+19960308 change: eliminated ownership test in qmail-alias.c. tnx DS.
+19960304 change: in SECURITY, ``six most recent sendmail security
+ holes'' -> ``seven most recent sendmail security holes.''
+19960303 qmail 0.73, beta.
+19960303 change: added SYSDEPS.
+19960303 cleanup: revamped select.h autoconfiguration.
+19960303 cleanup: revamped fork.h autoconfiguration.
+19960303 cleanup: revamped direntry.h autoconfiguration. target is now
+ direntry.h; auto-hasdrent.h is gone.
+19960303 change: tryflock.c now includes <sys/types.h>, for consistency
+ with lock.c. may affect portability.
+19960302 portability problem: under BSDI, can't set sticky on normal
+ files. dorks. impact: the new qlist doesn't work under BSDI;
+ be glad I test things before release. fix: qmail-alias and
+ qlist now use executable instead of sticky.
+19960302 change: gfrom now quotes >From and >>From etc. as well as From;
+ in other words, I'm switching from mbox format to mboxg format.
+19960302 cleanup: added gfrom.c. used it in qmail-alias.c, maildir2mbox.c.
+19960302 change: addbounce() now substitutes \n\n -> \n/ in reports,
+ and \n -> _ in recips. thus bounces can now be reliably parsed.
+19960302 change: if qmail-send had trouble reading the original message
+ or the list of addresses for a bounce, it used to give up and
+ send a bounce with "Oh no! I had trouble reading the rest of
+ your message" or some such. now it aborts the bounce attempt
+ and tries again later.
+19960302 cleanup: added qqtalk_fail(). used it in qmail-alias.c,
+ qmail-smtpd.c.
+19960302 bug: if mailforward() had trouble reading message (e.g.,
+ because of an I/O error), it marked an error but kept reading.
+ impact: could loop forever. fix: upon error, break.
+19960302 change: maildir2mbox now scans (restrictively) for return-path.
+19960302 change: qbiff now prints subject and body, up to 74 chars.
+19960302 change: added H_SUBJECT to hfield.
+19960302 change: qbiff now puts TO before FROM.
+19960301 cleanup: added fmt_str.c. used it in many places.
+19960301 change: qmail-send now says something if you've told it to exit
+ but it's waiting for some deliveries. tnx RN.
+19960301 change: qmail-alias -n now continues (with warning) if home
+ directory is sticky. tnx RN.
+19960301 change: improved usage messages in qmail-alias.c. tnx RN.
+19960301 change: put limit on length of addresses in qlist.
+19960301 change: added exit 99 support to qmail-alias. tnx RN.
+19960301 change: qmail-alias now exits immediately on temporary or
+ permanent error. rewrote section in qmail-alias.8 accordingly.
+19960301 cleanup: eliminated flagsuccesses from qmail-alias.c.
+19960301 change: added usermap.
+19960301 bug: failure to append to mbox was a permanent error. impact:
+ if mbox was temporarily unopenable (e.g., because fds were
+ low), mail would be incorrectly bounced. fix: failure is now
+ temporary. tnx DS.
+19960229 change: qmail-alias now preserves any envelope sender that
+ doesn't contain an @, not just <> and <#>.
+19960229 cleanup: revamped byte_* interface.
+19960229 cleanup: renamed str_cpy as str_copy.
+19960229 cleanup: added str_chr.c. used it in qbiff.c, qmail-smtpd.c.
+19960229 cleanup: added str_rchr.c. used it in qmail-send.c, quote.c,
+ qmail-remote.c.
+19960229 cleanup: added byte_rchr.c. used it in qmail-smtpd.c, spawn.c.
+19960229 cleanup: used USEREXT instead of RECIPIENT in qsmhook.c.
+19960229 cleanup: used USEREXT instead of RECIPIENT in qbiff.c.
+19960229 cleanup: removed j and k from rewrite() in qmail-send.c.
+19960229 portability problem: under HP-UX 10 and Solaris 2.5, can't
+ setgroups()/setgid() to the system's nogroup/nobody gid. dorks.
+ impact: inetd chokes, so all SMTP connections are rejected; and
+ ``alias'' mail, including postmaster, bounces. fix: in
+ INSTALL.ids, set up a separate powerless gid (tentatively
+ ``nofiles'') for qmaild and alias. tnx DS and PJG.
+19960229 change: qreceipt now uses qqtalk rather than qmail-inject.
+19960229 change: qlist now uses qqtalk rather than qmail-inject.
+19960229 change: incorporated qmail-setup patch from RN for better
+ error messages.
+19960228 change: added LSPAWN_BREAK in conf-unusual.h; used it in
+ lspawn.c. configurability requested by PJG.
+19960228 portability problem: on several systems, including everything
+ from DEC, select() on a pipe reader returns 1 if there aren't
+ any writers yet. pointed out by DS. impact: qmail-send chewed
+ up lots of CPU time. fix: trigger_set() now opens the pipe for
+ writing after opening it for reading. also added trynpbg1; on
+ working systems, no point in wasting the extra fd.
+19960228 change: qmail-alias uses .qmail sticky bit for forwardonly.
+19960228 change: qlist now sets sticky bit on .qmail file.
+19960228 change: un-documented +list.
+19960228 portability problem: on HP-UX and possibly other systems, the
+ supplementary group list does not include the gid. pointed out
+ by DS. impact: on those systems, tryshsgr could incorrectly set
+ hasshsgr; this would prevent qmail-send from running. fix: if
+ tryshsgr sees that getgroups() returns 0, now it actively sets
+ up a supplementary group list. added chkshsgr to make sure the
+ setgroups() will work.
+19960227 cleanup: eliminated GETSHORT in dns.c in favor of getshort().
+19960227 cleanup: deleted h->len < 3 test from qlist.c:dobody. tnx RN.
+19960227 change: replaced ~ with $HOME in INSTALL.mbox.
+19960227 change: added note about setgid-mail bits to INSTALL.mbox.
+19960227 change: added forward.1.
+19960227 change: modified forward to allow multiple addresses.
+19960227 change: modified forward to take an entire address, not just a
+ hostname.
+19960227 change: renamed qrelay as forward.
+19960227 change: added USEREXT support to qmail-alias.
+19960227 change: added -F to sendmail. the need for this was pointed
+ out by RN.
+19960227 change: added 2 bytes of slop in alloc().
+19960227 bug: received_setup() was not allowing space for the final \0.
+ impact: none; the line length is always between 65 and 75
+ characters, which gives at least 45 characters of slop with
+ existing malloc() implementations. fix: leave space. tnx NH.
+ note that the bug here is really in fmt_strncpy, which was
+ written before i was truly free of the curse of libc.a.
+19960227 change: added ALIAS_EMPTY in conf-unusual.h; used it in
+ qmail-alias.c. tnx PJG.
+19960227 change: added SPAWN_NUMD in conf-unusual.h; used it in spawn.c.
+19960227 change: added conf-unusual.h.
+19960227 cleanup: replaced sizeof(short) with 2 in dns.c.
+19960227 portability problem: on an Alpha, long is 64 bits. pointed out
+ by DS. impact: address lookups produced incorrect results on an
+ Alpha; qmail-makectl and qmail-remote failed. fix: replaced
+ sizeof(long) with 4 in dns.c.
+19960227 portability problem: on an Alpha, bzero() is declared properly
+ via sys/time.h. impact: couldn't compile on an Alpha. fix:
+ removed bzero() declaration from select.h. tnx DS.
+19960227 portability problem: under SCO, sys/file.h is not protected.
+ impact: couldn't compile under SCO. fix: include sys/types.h in
+ lock.c. tnx RN.
+19960219 change: added some .qmail-list hints to qlist.1.
+19960219 change: added +list support to qmail-alias.
+19960215 change: added THANKS.
+19960212 bug: foo was not initialized in qrelay.c. impact: depends on
+ the machine; on some machines, no effect; on other machines,
+ guaranteed core dump. fix: initialized foo. tnx DS.
+19960209 qmail 0.72, beta.
+19960209 change: qmail-alias now replaces dot, not slash, with colon.
+ also, qmeopen() makes sure that .qmail file is S_IFREG; I hope
+ this doesn't cause portability problems.
+19960209 change: added success-reporting procedure to INSTALL.
+19960208 change: added VERSION.
+19960208 change: added qlist2.
+19960208 change: revamped qlist interface. tnx RN.
+19960208 change: improved an error message in qlist.c.
+19960208 change: added qrelay. added relay section to HOWTO. tnx DS.
+19960208 cleanup: included substdio.h in qqtalk.h.
+19960207 bug: prioq_delmin() wasn't guaranteeing heap structure on the
+ last element. impact: scheduled passes could have been delayed,
+ conceivably as long as half an hour. fix: prioq_delmin() now
+ checks when it can safely move the last element.
+19960207 change: added maildirmake.1, maildir2mbox.1.
+19960206 change: revised logo paragraph in THOUGHTS.
+19960206 change: replaced with in examples.
+ is a real domain... [sigh]
+19960206 change: added qreceipt.1.
+19960206 portability problem: IRIX doesn't have vfork. pointed out by
+ DS. impact: couldn't compile under IRIX. fix: added fork.h,
+ tryvfork.c.
+19960206 portability problem: IRIX doesn't have ranlib. pointed out by
+ DS. impact: couldn't compile under IRIX. fix: added IRIX
+ section in
+19960205 cleanup: removed warning from substdio_copy() documentation; in
+ fact, substdio_copy() can be used safely on a fed substdio.
+19960205 change: added qbiff.1.
+19960204 change: implemented localnet. removed relevant paragraph from
+19960204 change: in qmail-remote.8, explained the dangers of smarthost.
+ tnx IS.
+19960204 change: implemented virtualdomains wildcards. tnx JLH.
+19960203 change: qmail-send now handles virtualdomains _after_ locals.
+ updated INSTALL.qsmhook appropriately.
+19960203 change: added note to INSTALL.alias about ~ftp, ~www, ~uucp
+ being owned by root.
+19960130 cleanup: in qlist.c, renamed flagremoved as flagwasthere.
+19960130 bug: qmail-send did not pay attention to flagexitasap in
+ pass_dochan(). impact: qmail-send would happily start new
+ deliveries even if it wanted to exit. fix: qmail-send now
+ returns immediately in pass_selprep() and pass_dochan() if
+ flagexitasap.
+19960130 change: in qlist.c and qlist.1, renamed ext as list.
+19960130 change: in qlist.c and qlist.1, renamed manager as owner.
+19960129 qmail 0.71, beta.
+19960129 change: mentioned djb-qmailbeta in README. tnx MWE.
+19960129 change: added a note to INSTALL.mbox making clear that
+ Mailbox is in mbox format. tnx MWE.
+19960129 change: qlist now warns you if it didn't see any cmds. tnx RN.
+19960129 change: incorporated qlist patch from RN to refuse double subs.
+19960129 change: added qlist.1, contributed by RN. mangled it a bit.
+19960129 bug: comment was not allowed in ``phrase (comment) <route>'';
+ pointed out by RN. impact: some correct address lists could be
+ mis-parsed by qmail-inject or qlist. fix: token.c now allows
+ TOKEN_COMMENT in the appropriate scan.
+19960128 change: added a logo paragraph to THOUGHTS.
+19960127 change: implemented rcpthosts.
+19960127 change: split up some uses of putflush in qmail-remote,
+ qmail-smtpd, spawn.c. eliminated NODELAY and corresponding
+ paragraph in THOUGHTS.
+19960127 change: added quote2(). used it in qmail-alias, qmail-send,
+ qreceipt. now addresses are properly quoted in the From, To,
+ and internal Return-Path of bounces; the From and To of
+ receipts; and the Return-Path/RPLINE of delivered messages.
+ removed relevant paragraph from THOUGHTS.
+19960127 change: in RFCLOOPS, documented fact that Delivered-To address
+ is conventionally not quoted.
+19960127 change: knocked default SMTP timeouts down to 20 minutes.
+19960127 change: added INSTALL.ids. tnx RN.
+19960127 change: in INSTALL, noted that nogroup should already exist.
+19960127 bug: pass_selprep checked pqchan[c] even if pass[c].id. impact:
+ qmail-send wasted CPU time whenever more than one message was
+ waiting on a blocked channel. fix: pass_selprep now checks
+ !pass[c].id.
+19960127 bug: programs invoked from qmail-alias were immune to SIGPIPE.
+ impact: a delivery pipeline such as |yes|head -1000 would loop
+ forever, since yes does not check for write errors. fix: added
+ signal_uninit(). used it before execvp in qmail-alias. [sigh]
+19960127 cleanup: added date822fmt.c. used it in newfield.c, qmail-queue.
+19960127 cleanup: added fmt_uint0.c. used it in myctime.c, newfield.c,
+ qmail-queue.
+19960127 cleanup: added dnsdoe.c. used it in dnscname, dnsfq, dnsip,
+ dnsmxip, dnsptr.
+19960127 cleanup: eliminated temp from dnsfq.c.
+19960127 bug: gen_allocdefs was making assumptions incompatible with the
+ alloc_re interface. impact: qmail-send would dump core if you
+ ran out of memory. fix: changed alloc_re interface.
+19960126 portability problem: some versions of Linux don't have
+ net/route.h. pointed out by RN. impact: couldn't compile under
+ those versions. fix: ipme.c no longer includes net/route.h;
+ hopefully this won't cause new portability problems.
+19960126 change: added chmod instructions to INSTALL and INSTALL.alias.
+ tnx RN.
+19960126 change: INSTALL now refers to the traditional sendmail spot
+ (/usr/lib), not the BSD 4.4 spot (/usr/sbin). tnx RN.
+19960126 change: make auto-uids.h now creates auto-uids.h.tmp first.
+ thus, if someone disobeys the installation instructions, and
+ his make fails to remove targets upon error, he'll still be
+ okay. tnx RN.
+19960126 change: added forgeries.7.
+19960125 cleanup: eliminated flagverbose, flagmetoo in sendmail.
+19960125 cleanup: added substdio_copy.c. used it at several spots.
+19960125 cleanup: added constmap.c. qmail-send now uses constmap for
+ locals and virtualdomains. this will speed things up: no
+ problem now to have thousands of virtual domains. removed
+ relevant paragraph from THOUGHTS.
+19960125 change: added linux section in find-systype. this will affect
+ linux-* systypes. tnx RN for relevant info.
+19960124 change: added -od, -oe, -p, -f to sendmail. the need for
+ these was pointed out by TN.
+19960124 bug: qmail-smtpd was reading from descriptor 1. impact: none;
+ in normal use, both 0 and 1 point to the network. fix: changed
+ 1 to 0.
+19960124 bug: qmail-alias treated any .qmail open failure as permanent.
+ impact: if a .qmail file was temporarily unopenable (e.g.,
+ because of NFS), it was incorrectly ignored. fix: qmail-alias
+ now dies QLX_SOFT on any open failure other than ENOENT.
+19960124 change: added freebsd section in find-systype, same as bsd.os
+ section. this will affect freebsd-* systypes.
+19960124 cleanup: find-systype now immediately converts sys to lowercase.
+19960124 change: qmail-setup now copies man pages into /var/qmail/man;
+ qmail-check checks /var/qmail/man. using .0 style, which might
+ cause trouble on various machines, but better than not trying.
+19960124 change: in qmail-remote.c, changed perm_control to temp_control
+ (and D to Z, thanks); thus failure to read control files (e.g.,
+ because of permissions) is now a temporary error.
+19960124 bug: in qmail-remote.c, temp_chdir() used D, not Z. impact: if
+ chdir() to CONF_HOME failed (e.g., because of NFS), message
+ would be bounced. fix: changed D to Z.
+19960124 change: reorganized README.
+19960124 portability problem: Linux has the fifo kernel bug that I had
+ hoped I'd never run into. impact: messages under Linux (and any
+ other systems with this bug) were picked up only in sweeps, not
+ instantly. fix: triggerpull.c now writes a byte (non-blocking)
+ to the fifo. updated INTERNALS accordingly.
+19960124 bug: in qmail-remote.c, if quit() saw a remote write error, it
+ would call writeerr() even though a message report had already
+ been produced. impact: the mess report would include an extra
+ ``ZConnected but communications failed,'' which was confusing
+ to humans. fix: quit() now simply skips the wait-for-QUIT
+ smtpcode() upon write error.
+19960124 portability problem: Linux does not have SIGSYS or SIGEMT.
+ impact: couldn't compile under Linux. fix: added appropriate
+ ifdefs in signal.c.
+19960124 qmail 0.70, beta.
