If you're willing to live on the bleeding edge. Dan Bernstein's 'qmail' 
does a pretty good job of handling large mailing lists.  I have 
philosophical differences with a few of its design decisions, but 
overall it's the closest I've seen to "the right way to do it".  You 
can get it by anonymous FTP from koobera.math.uic.edu in 
pub/software/qmail-0.75.tar.gz.  Note that it is _significantly_ 
different from sendmail; be prepared for a bit of a shock.

I've spent plenty of time inside zmailer, because the BorderWare 
Firewall Server uses it.  About once a week we discuss whether it would 
be possible to trash it and put in something else.  It's a much worse 
memory hog than sendmail, aside from all its other problems.

Hmm.  My inclination would be to configure the listening sendmail to 
queue everything except local deliveries, and then run maybe 3 other 
sendmails processing the queue for outgoing messages.
