Why? Sounds like mail masq'ing.

Depends on what you are trying to do. Outgoing mail should be "easy",
incoming mail wouldn't make sense unless you have a domain name (of
some sort).

Hmm... sounds like you didn't masq the envelope.

I used:
canonical_maps = hash:/etc/postfix/canonical
to map root to my normal email (in case my box dies,
it might have left a clue there).
root [EMAIL PROTECTED]
and
sender_canonical_maps = hash:/etc/postfix/canonical_sender
to map a user without a real email adderss to my email address
user [EMAIL PROTECTED]
and finally:
recipient_canonical_maps = hash:/etc/postfix/canonical_receiver
to have mail to the user without email be delivered locally
if send from my box.

There's no way around specifying your local acconuts as you have to
tell your mta that it's only authorative for a set of accounts. You
could automative things using something like make with a dependency on
your /etc/passwd and some script to filter out the accounts that you
don't care about.

Ok.

You probaly need to enable relay for your local network, but otherwise
it sounds like you're on the right path.
