In which case I should indeed be able to tweak submit.mc to do what I
need.  Excellent.

I really, really wish I could.  But the reason I'm having to dive into
mimedefang/SA is because my budget has been frozen, so I had to dump

The budget I did have had to be spent on MailChannels' TrafficControl,
a light weight connection management layer that sits between sendmail
and the world, multiplexing sendmail sessions, getting rid of about
80% of connections before starting any heavy lifting through
sendmail/milters.  Lets me handle up to about 2000 concurrent
connections per box with only 30 or so sendmails running.  If I turn
TrafficControl off, I last about 30 seconds before my little farm
comes grinding to a halt!
