Relay access denied in post fix
Posted on 2014-09-21
We have setup postfix, dovecot on our new server and have no issues sending or receiving e-mails from the server directly. However, when we try to send mails out
from outlook/thunderbird, it fails with the following error message(s):
## postfix/smtpd: NOQUEUE: reject: RCPT from abc.domain.net[<ip_address>]: 454 4.7.1 <email@example.com>: Relay access denied; from=<firstname.lastname@example.org> to=<email@example.com> proto=ESMTP helo=<mydel>
I have added domain.net to mynetworks, but still I get the same error.
