+As you've seen, qmail has essentially no pre-compilation configuration.
+You should never have to recompile it unless you want to change the
+qmail home directory, usernames, or uids.
+qmail does allow quite a bit of easy post-installation configuration. If
+you care how your machine greets other machines via SMTP, for example,
+you can put an appropriate line into /var/qmail/control/smtpgreeting.
+But this is all optional---if control/smtpgreeting doesn't exist, qmail
+will do something reasonable by default. You shouldn't worry much about
+configuration right now. You can always come back and tune things later.
+There's one big exception. You MUST tell qmail your hostname. Just run
+the config-fast script:
+ # ./config-fast
+config-fast puts into control/me. It also puts it
+into control/locals and control/rcpthosts, so that qmail will accept
+mail for
+You can instead use the config script, which looks up your host name in
+ # ./config
+config also looks up your local IP addresses in DNS to decide which
+hosts to accept mail for.
+(Why doesn't qmail do these lookups on the fly? This was a deliberate
+design decision. qmail does all its local functions---header rewriting,
+checking if a recipient is local, etc.---without talking to the network.
+The point is that qmail can continue accepting and delivering local mail
+even if your network connection goes down.)
+Next, read through FAQ for information on setting up optional features
+like masquerading. If you really want to learn right now what all the
+configuration possibilities are, see qmail-control.0.
