Sendmail timeouts

I've been trying to set some more aggressive timeouts in
sendmail than
the defaults. This is to stem the tide of stale connections
(most
seemingly from spam sources) that keep chew up resources on
my mail
front-end. The various things I've tried have not really
helped all that
much. And the sheer number of timeout values make it's
difficult in
choosing what to tune.

So my plea to the collective list wisdom is what do you
folks use? What
values would you recommend I try?

I looked at the RFC's recently for something else and there
are recommendations... typically of about 5m for all of
'em.

Look in RFC 2821... There are some values mentioned.
