Blocked port 25 and Gmail

March 16, 2014 4.7k views
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?

Open a ticket, DigitalOcean blocks ports to your Droplet when there is abuse information on the IP.
No i have also create a other question about strange outgoing mails.

Have you configured POSTFIX to use Port 465 or 587 with gmail instead?

There is something going wrong
My postfix sends emails to all kind of unknown email accounts outside (hotmail, gmail etc)

When i do tests it says my mailserver is not relay. Also when i try using termini is says: Relay Acces Denied

But i see lot of outgoing emails used my email account thats configured on my server.

Only explanation i have that they know my password.. but it is a strong password. Or are there other reasons ?
