[please don't top post]
The "ares2" server is submitting mail via the postfix sendmail(1) command,
with an envelope from address of "root". Postfix will add @$myorigin to
unqualified user names, when using the recommended default
"append_at_myorigin = yes".
The "hebe" server is submitting mail !TO POSTFIX! via SMTP using an
envelope from address of "", so the append_at_myorigin
parameter does not apply, as the from address is already fully qualified.
You may note this header from hebe:
Received: (from root at localhost) by hebe.dog.net (8.12.11/8.12.11/Submit) id
j3KLWUlQ005987 for ; Wed, 20 Apr 2005 16:32:30 -0500
This header is apparently inserted by the real sendmail program, and
sendmail is changing the sender address to "".
So you have a couple tasks...
- Uninstall sendmail from hebe. Make sure you don't clobber the postfix
sendmail(1) compatibility program.
- Investigate the masqurade_domains parameter to rewrite internal domain
names to a consistent external name.
