Thanks for your help. The memory on this beast is maxed out at a screaming 512Meg. It's an IDE structure but we just put in an emergency PR for a 15Krpm scsi disk for /var/spool/mqueue and found a source for cheap scsi cards. I've also made it a cache-only nameserver.
You also want a separate SCSI disk system for the mailman queue directories.
You should get a copy of Nick Christenson's book _sendmail Performance Tuning_, and apply the recommendations from there. This includes things like enabling filesystem journaling or softupdates (depending on the OS), mounting the filesystem "noatime", using striping+mirroring for the underlying disk subsystem (might require external drive arrays), etc....

For MTA tuning tipes, see <http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq06.002.htp>, <http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq06.003.htp>, <http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq06.004.htp>, or <http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq06.005.htp> depending on whether you're running Exim, sendmail, postfix, or qmail (respectively).
If these things don't resolve it, I'm gonna have to break it up into perhaps 26 sublists (A-Z) and make the main list an umbrella list.
That would help on the mailman side, but not the MTA.
Ultimately, we're gonna need a faster machine but layer 8 of the OSI model (political) works slowly here ;)
Spend your money on getting more RAM (or a machine that can handle more RAM), the more the better -- I'd go for 2-4GB or more, if possible. Spend your money on getting an improved disk subsystem (e.g., an external high-speed drive array, or maybe even a solid-state disk). Spend your time getting the rest of the software configuration right to make the best of what you have.
