Email problems 25TCP PORT PLESK

Hello everyone, i’m having an issue. I’m new in DO and i don’t know how much days they need to reply a ticket. I’ve installed plesk on my droplet and tried to configure domain’s email. I can receive mails but i can’t send It.

Plesk says me that I’ve the TCP 25 PORT closed but with netstat i can see that it’s open.

No DO’s firewall Is configured so there aren’t conflicts.

Dovecot Is running perfectly.

When i try this :

telnet 25

The response Is :

telnet: Unable to connect to remote host: Network is unreachable

No idea of what to do and how to solve. Maybe DO blocks ports ? But why with netstat i can see them open?

Thanks to all

Hi there @KyrosWeb,

I believe that for new accounts outgoing TCP connections on port 25 are blocked for security reasons.

I would recommend trying with port 587 or 465 instead.

Let me know how it goes! Regards, Bobby
