I am unable to receive emails from external sources (gmail etc.) I can receive emails from internal users. i.e. on the same server. However, the emails from external servers are bouncing back. The error from Gmail is
“The response from the remote server was:
451 relay not permitted!”
I can send emails to both internal and external. But unable to receive emails. I have also checked logs in /var/logs/maillogs, but I don’t see anything there either.
Any suggestions to resolve this?
