FWIW, I'm running mailman on an openbsd system w/ 64M ram and 200M swap
on an old Compaq P90.  Active software includes mailman (2.1.5), apache, 
postfix, and bind.  Not very speedy, but works well enough for <50 member 

top tells me:
Memory: Real: 23M/47M act/tot  Free: 11M  Swap: 41M/200M used/tot

There are tiny web and smtp servers, but I suspect that most of them will
be missing -some- feature that mailman needs. While trying to shoehorn a
working system onto some "interesting" platform can be fun, life will be
easier if you can add a bunch of memory.
