So are you saying, I could tell mailman to group in chunks of say 50 and
even though I have 150 people on the list, mailman would deliver 3 batches
of 50 to cover them all? Thereby I can keep below my 100 / email limitation
that this service provides me?

Is this different than 
http://www.dyndns.com/services/mailhop/outbound.html
Or
http://www.no-ip.com/services/managed_mail/inbound_port_25_unblock.html

Can you (or anyone) suggest one that "just works" with my setup (above)?

Thanks for the reply.
