I've run postfix (instead of sendmail) with rather 
good results; I had a small (2000) member list a 
while back that I was administering; it cut the average
delivery time by several minutes.  I think a bulk of the 
time savings had to do with delivering multiple names 
at once to the same domain (like aol.com);  I can't say 
I really understood how it all worked... only that it 
was quite a bit faster.

I've been running mailman instead of majordomo; but
I think that it is slower... but maybye this is my
imagination.  Isn't majordomo perl?   There has to
be a list server written in C somewhere....

> upgrading hardware is a possibility

I guess it would be good to look at 
memory/cpu usage during a period when
several messages hit at once.   I'm not
sure how to best monitor this...

How big is the list?  20,000 ?  
How big is the pipe?  Does it go 
directly to two or more backbones?

Wish I could help more...
