announce: rejectutils patch

The rejectutils patch adds several standalone programs for selectively 
rejecting messages:


# qmail-queue(8) wrappers

- qmail-qfilter-smtpd-queue runs the sequence of programs in 
control/smtpfilters via qmail-qfilter.
- qmail-qfilter-ofmipd-queue runs the sequence of programs in 
control/ofmipfilters via qmail-qfilter.


# qmail-qfilter(1) filters

- qmail-qfilter-viruscan is a repackaging of Russ Nelson’s viruscan 
patch.


# RCPTCHECK wrapper

- qmail-rcptcheck runs the sequence of programs in control/rcptchecks, 
rejecting if any of them reject.


# RCPTCHECK checkers

- qmail-rcptcheck-realrcptto is a repackaging of Paul Jarc’s 
realrcptto patch.
- qmail-rcptcheck-badrcptto is a repackaging of Ward Vandewege’s 
badrcptto patch.
- qmail-rcptcheck-qregex is a repackaging of most of Andrew St. Jean’s 
qregex patch.


If you’re looking to SMTP-reject messages according to multiple 
criteria, and/or are dealing with qmail-smtpd(8) patch conflicts, this 
patch may be useful to you.
