Minor bugfix. If you use morercpthosts, after a failed authentication
attempt, if the client attempts to send mail to a domain which is not listed in rcpthosts, qmail-smtpd is unable to read morercpthosts.cdb. Instead, it sends "421 unable to read controls (#4.3.0)" and drops the connection. This patch fixes this bug by closing file descriptor 3 (only if necessary) in the authentication child process rather than the parent process. Credit: Tom Clegg
