What is it?

fdm is a program to fetch mail and deliver it in various ways depending on
a user-supplied ruleset. Mail may be fetched from stdin, IMAP or POP3
servers, or from local maildirs, and filtered based on whether it matches a
regexp, its size or age, or the output of a shell command. It can be
rewritten by an external process, dropped, left on the server or delivered
into maildirs, mboxes, to a file or pipe, or any combination.

fdm is designed to be lightweight but powerful, with a compact but clear
configuration syntax. It is primarily designed for single-user uses but may
also be configured to deliver mail in a multi-user setup. In this case, it
uses privilege separation to minimise the amount of code running as the
root user.

Why this page?

I happen to be the debian maintainer for fdm.
This is a meta-page about fdm itself and its debian package in order to
assist users in case something goes wrong.

Do you keep track of the package somewhere?

Why yes, I do.

Holy smoke, I hit a bug...

Working with fdm's upstream

Often, reported problems do require the involvement of fdm's author.
Luckily, we're dealing with a pretty friendly upstream here. :)
