This is mailfront, a package containing customizeable network
front-ends for mail servers. It contains complete SMTP and
POP3 front-ends as well as an authentication module for
IMAP.
Two SMTP back-ends are provided. One delivers mail to
qmail-queue, mimicking most of the behavior of qmail-smtpd,
with the addition of support for SMTP AUTH. The other
rejects all SMTP commands if $SMTPREJECT is set, and execs
its command line otherwise (in order to run the above
program).
