Question
Blocked port 25 and Gmail
- Posted March 16, 2014
Hi All,
I have blocked out port 25. I can receive emails but when i send email from Gmail to my own email behind Postfix it will not deliver.
When i open port 25 again all gmail emails got delivered. Is there something i can do about that?

There is something going wrong <br>My postfix sends emails to all kind of unknown email accounts outside (hotmail, gmail etc) <br> <br>When i do tests it says my mailserver is not relay. Also when i try using termini is says: Relay Acces Denied <br> <br>But i see lot of outgoing emails used my email account thats configured on my server. <br> <br>Only explanation i have that they know my password… but it is a strong password. Or are there other reasons ?
Have you configured POSTFIX to use Port 465 or 587 with gmail instead? <br> <br> <br>https://support.google.com/mail/troubleshooter/1668960?hl=en#ts=1665018,1665144
