I accidentally replied to a thread instead of starting my own..oops..
Postfix Version: postfix-2.5.1-1.rhel5
I have an internal relay with an external NAT.
The internal relay is not visible to the outside..
The receiving destination gives the error:
--
550 [PERMFAIL] xxx.xxx.net requires valid sender domain (in reply to
RCPT TO command))
--
My question
What is the most efficient way to
"rewrite" the sender address with a valid smtp address
to a "specific" domain.
I only need to do this for 1 destination domain..
Thx
