	There are far too many variables in the equation to be able to 
simply throw out some numbers.  Odds are that you're going to have to 
read a number of Mailman FAQ Wizard entries and try some things out 
and see what works for you.

	Please go to the FAQ Wizard at 
<http://www.python.org/cgi-bin/faqw-mm.py> and search for 
"performance" and also search for "tuning".  Pay particular attention 
to the entry at 
<http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq06.003.htp> 
You should also take a look at the entries returned by searching for 
"VERP".

	If you want to go further down this road, beg borrow or steal a 
copy of Nick Christenson's book "Sendmail Performance Tuning".
