Hi,
I have the following in main.cf:
soft_bounce = no
unknown_address_reject_code = 550
Still, postfix server rejects mail from our exchange server with 450
instead of 550:
Dec 3 15:41:32 mx2 postfix/smtpd[40509]: NOQUEUE: reject: RCPT from
exchange.senderdomain.org[D.D.D.D]: 450 4.1.2 <some...@recipientdomain.org>:
Recipient address rejected: Domain not found; from=<some...@senderdomain.org>
to=<some...@recipientdomain.org> proto=ESMTP helo=<exchange.senderdomain.org>
IP address of exchange server is in mynetworks.
Any help appretiated.
Here's postfinger output:
