mailfront - 2.12-2 main

mailfront is a set of customizable network front-ends for mail servers.
It contains complete SMTP, QMQP, QMTP, and POP3 front-ends as well as an
authentication module for IMAP. The mail delivery front-ends also contain
internal address filtering features.
.
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).
