mailfilter - 0.8.6-3 main

Mailfilter is very flexible utility for UNIX (-like) operating systems
to get rid of unwanted e-mail messages, before having to go through the
trouble of downloading them to the local computer. It offers support for
one or many POP3 accounts and is especially useful for dialup connections
via modem, ISDN, etc. Install Mailfilter if you'd like to remove spam from
your POP3 mail accounts.
.
With Mailfilter you can define your own filters (rules) to determine
which e-mails should be delivered and which are considered waste. Rules
are Regular Expressions, so you can make use of familiar options from
other mail delivery programs such as e.g. procmail.
.
If you do not get your mail from a POP3-Server you don't need Mailfilter.
