Majordom isn't going to be able to handle the separate lists in
any straightforward manner. People will have to know which
sublist they are on to unsub, and you'll have to have config
files for each list.

If you're concerned about delivery times, stay with one large
list and get bulk_mailer. Bulk_mailer sorts by domain, and
attempts to group all mail for one domain in a single envelope.
Otherwise, it splits the job into small chunks and passes them to
sendmail.

Bulk_mailer is mentioned in the faq.
