Bug#118149: IT: pop-before-smtp -- watch log for pop/imap auth, notify Postfix to allow relay

Package: wnpp
Severity: wishlist
X-Debbugs-CC: debian-devel@lists.debian.org


Spam prevention requires preventing open relaying through email servers.
However, legit users want to be able to relay. If legit users always
stayed in one spot, they'd be easy to describe to the daemon. However,
what with roving laptops, logins from home, etc., legit users refuse to
stay in one spot.

pop-before-smtp watches the mail log, looking for successful pop/imap
logins, and posts the originating IP address into a database which can be
checked by Postfix, to allow relaying for people who have recently
downloaded their email.

Contrary to other similar tools pop-before-smtp needs no hacking in the
mail daemons. On the other hand it requires the pop3/imap daemons to run
on the same machine as pop-before-smtp and postfix.
