fdm - 1.9+git20181219-1+b2 main

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.
