[Exim] Mailing list options?

I'm using Exim and gnu-pop3d with the virtual domains patch. Can anyone
recommend a good mailing list manager that supports multiple lists at
virtual domains? I really liked mailman until I read the HOWTO. It looks
like it doesn't support multiple domains very well. Of late I've been
reading up on Majordomo.

TIA,
