Problem:
Our mail server sends mail from cct.lsu.edu. A group of users want
to send mail and have their address be stellar-group.org. We already
have this in mydestination so we do /get/ email sent to that domain,
but at current you can't send email /from/ that domain and have the
address show up as that. Is there a way to do this in postfix?
Typically the sender information is set in the user's mail client.
If they send mail with the new domain as sender, postfix shouldn't
alter it.
It's possible for postfix to do the mapping using canonical_maps,
but the first choice should be configuring the user's mail client.
If this isn't working as expected, please send logging demonstrating
the problem, and your "postconf -Mf".
