that is a very interesting idea.
Our problem is that our mail front ends and our mail backends
are distributed across many machines. And that we have
sendmail at the core.
So we have some fundamental design questions to look at.

% John, I ran into the same thing during my test with Cyrus. The problem
% was how to call Procmail from Postfix for destination to Cyrus IMAP. I'm
% not certain that this is what you ran into but if so here's the way to
% make Postfix call your procmail recepies and then deliver to the Cyrus
% IMAP store:
%
% In /etc/postfix/main.cf modify your mailbox_transport parameter to this:
%
% mailbox_transport = cyrus_procmail
%
% The cyrus_procmail definition is one you will create in
% /etc/postfix/main.cf.
%
% Back up your modification in main.cf with this added line in
% /etc/postfix/master.cf:
%
% cyrus_procmail unix - n n - - pipe
% flags=R user=cyrus argv=/usr/bin/procmail -m /etc/procmailrc ${user}
%
% This calls procmail in "general purpose" mode and will pass the 'user'
% argument to /etc/procmailrc... a parameter that as I understand it is
% usually lost.
%
% Finally, simply add the following to your /etc/procmailrc file as best
% suits your needs:
%
% ###########################################################
% ### Deliver it to the user inbox
% ###########################################################
%
% :0
% | /usr/cyrus/bin/deliver -a $1 -m user.$1
%
%
% That's it, happy people!
