Yes its possible. I do that with sendmail for a friend's domain I host
Here's an anonymised real operational sample from my server with comment added
/etc/mail/virtusertable
hostmaster at sparedomain.com hostmaster
hostmaster at www.sparedomain.com hostmaster
# I take the hostmaster cos hes not competent to.
friend-local-acc-on-my-host at sparedomain.com sparedomain-default
# friend-local-acc-on-my-host@ is redundant as
# done by default, but left for clarity.
# could also go to secretary-of-friend at anywhere-else.com
# example at sparedomain.com some at where_else
@sparedomain.com sparedomain-default
# this collects all of
# friends-new-colleague-he-hasnt-told-me-about at sparedomain.com
# random-guess-by-spammer at sparedomain.com
@www.sparedomain.com sparedomain-default
# divert any mail re friends web site to the friend.
/etc/mail/aliases:
# switchable choice depending if I POP serve the friend or forward.
sparedomain-default: friend at some-other-domain.com
# sparedomain-default: friend-local-acc-on-my-host
PS I skimmed but didnt really understand Matthew's posting, (not
saying its right or wrong, just didnt grasp it), but I have sendmail
working fine for my @berklix.org & for a friend's @surfacevision.com
So Paul, you can use sendmail for this if you want.
Cheers,
Julian
