SMTP disconnected problem  [SOLVED]

Post by lmarcos »

I messed yesterday with my server permissions and now I can't have the smtp open.
Here is the dashboard monitor showing the smtp disabled.

And here are the firewall rules.

So I'm getting SMTP Error: RCPT TO command failed <x****@*****.xxx>: Temporary lookup failure 451 4.3.0

Thanks for your help :D

This is what I did to get postfix listening again
Edit /etc/postfix/master.cf
Remove the # symbol in front of the line:
#submission inet n - n - - smtpd
and restarted either with
service postfix restart
or postfix reload
