Cool. I'll update the FAQ entry with this info.

Can you get more process-specific information about Mailman, apache,
postfix, and BIND?
On the BSD system I previously quoted from, I was running commands like:
% ps auxww | grep -i mailman | awk '{ sum+=$5 } END { print sum }'
... in order to get the VSZ (virtual size) information, and using
"...$6..." to get the physical RAM usage.

Yup. But it would be interesting to do some tests and see if we can find
out what a reasonable minimum system configuration really is for these
kinds of things. Your 64MB/200MB system is smaller than I thought would
work even moderately well (based on the information I had gathered), but
it may be that we could cut things down even more.
