I have a very wierd setup as I transition from the current email
to a sendmail+cyrus based email system. My email currently comes
into the internet, through a spam assassin filter, is sent to a
server inside my network, that server forwards the message(s) to
a POP server on the outside of my firewall.

mail->filter->server+cyrus->server+pop
^ ^
| |
firewall firewall

The server+cyrus is at the moment really only a fowarding box using
the server+pop as a smarthost. I want to test delivering any messages
sent to me directly to the cyrus server on server+cyrus, stopping
any messages in server+cyrus and not sending the messages on to
server+pop.

I see a line in sendmail.cf calling procmail the local delivery
agent (Mlocal, P=/usr/bin/procmail, ...). How can I test that
procmail will be used and how can I force any messages to me to
local delivery. Seems like all messages must pass through procmail
and for those messages directly to me, procmail can call deliver.
What about the messages for everone else? If the message is not
handled by procmail, will sendmail go ahead and forward the message
as it is doing now?

Fedora Core 5 with recent patches
latest sendmail
latest cyrus
latest procmail

Or maybe turn the problem around. Is it possible to change the sendmail
setup so that for every message that comes in procmail is called for
delivery and inside procmail there is a check for my user id, if my
user id the message is given to deliver for inserting into cyrus otherwise
the 'lmtp' program is used to forward the message to server+pop for
pop delivery?
