Using procmail to auto-file messages.

[<donw@examen.com>]

I've got a mail account on one of my servers which is accessed by a few
individuals.  Messages in this account are broken up by month;
therefore, messages for each month live in their own folder.  Is there a
way I can rig up a .procmailrc, such that it will auto-file messages
into the appropros folder based on the message date, in addition to
creating new IMAP Maildirs[1] when needed?

I can write a Perl script to do this, but I'd rather use an existing
tool.

[1] We use qmail and courier-imap.
