Same setup that we have.  For load reasons, we want to do all the
checking on our relay machines, not where the mail is delivered.
Here's what we do.

Sendmail can be configured to queue only.  Sendmail can also
be configured to empty a queue.  We have one sendmail configured
to receive mail, and put it in the directory mqueue1, and
another sendmail configured to empty the queue in mqueue2.

A small C program was written to move the files from one
directory to the other, locking and checking (currently using 
grep) for SirCam.

If sircam is found, it is moved into mqueue3.
