Hi, after a lot of research I noticed that Digitalocean has blocked port 25 for my account. I installed Postal SMTP Mail Server on my VPS but it shows an error when sending emails.

It shows an error when I try to connect to another SMTP while I can connect my SMTP via other SMTP. This means that the outgoing port 25 is blocked.

Shows this error in CLI:

root@mail:~# telnet 25 Trying… telnet: Unable to connect to remote host: Connection timed out

Shows this Error in my Server:

No SMTP servers were available for Tried,,,, and

Plz open outgoing port 25 for my account.

I was on the same boat, after a couple messages with the support team, this fixed it:

sudo ufw allow 25
sudo ufw reload 

Yeah I just joined Digital Ocean and you guys provide a great service. I loved how clean it was to set up a droplet. But not having access to SMTP ports is deal-breaker. You guys should just let your clients use the port. It’s a shame I would have loved to host my sites in here.
