Yes, I have it working on a UML instance with only 64mb ram, and 256mb
swap. But you do really have to watch your memory consumption with
Mailman. I've never run Dovecot (I run Courier-IMAP), but so long as
your not running anything else besides what you've mentioned (Dovecot,
Apache, and Mailman), you should be cutting it just about even. I'd
look into cutting some of the un-used modules out of Apache.

Yes, Xen is currently faster, but I've recently heard this from Jeff
Dike a couple days ago:
"Also, I'm getting UML help from other people at Intel, and those
patches have started going into my tree. We're separating out the
userspace code from the kernel code in preparation for a ring 0 port
Which I believe should put UML back in the running right alongside Xen
with no overhead.
Personally, I'm rooting for UML, but that's probably mostly because
that's what I'm currently setup with. It's come a long way, and it's
sitting pretty stable. Xen isn't nearly as mature, but I love watching
the progress of both of them. Both are really great projects.
