With sendmail (the default FC3 mail server), you add your list of
domains, one per line, to /etc/mail/local-host-names and then add
entries for each account at each domain to /etc/mail/virtusertable,
specifying which local account that user's mail should be delivered to,
e.g.

joe at example.com		joe1
joe at other.com		joe2
postmaster at example.com	root
@example.com		jim

Then run "make -C /etc/mail"

The first entry delivers mail for joe at example.com to local account joe1

The second entry delivers mail for joe at other.com to local account joe2

The third entry delivers mail for postmaster at example.com to local
account root (or whoever root has been aliased to in /etc/aliases)

The last entry is a catch-all mailbox that delivers mail for anyone in
the example.com domain not otherwise specified to local account jim

Quite easy really.
