    You can have a "global" procmailrc at /etc/procmailrc, and then
let customers edit their own personal .procmailrc on an as-needed basis.

    Exim has its own filtering that can reside in, say, a .forward
file, but does not support the Maildir format (which procmail does).
Check the Exim docs for more on Exim's built-in filtering.

    I'm using it right now to deliver to Maildirs.  I haven't done the
filtering side of things yet (but I have no reason to think I'll have any
problems, procmail is already doing the delivery).  I'm going to offer a
web-based interface for editing the .procmailrc files.


    Procmail is fairly expensive to launch for every email.  My view
on this is that processing power is cheap, in fact, one of the cheapest
components in the system.  (I'm doing a load-balanced setup so I can add
$1500 nodes on an as-needed basis.)
