My issue has been solved by Digitalocean support team, Thank you all Who tried to solve my issue…

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 

Hello all,

I’ll recommend checking this article:

Port 25 might be closed for new accounts. This is something we have been doing to reduce spam on our network. Please do not think that we are accusing you of sending spam, it is more that we simply cannot accurately determine who is going to send it.

Dedicated email deliverability platforms are better at handling deliverability factors like IP reputation. To send mail from DigitalOcean, we recommend using SendGrid:

SendGrid DigitalOcean Marketplace 1-Click App

Even on older accounts where SMTP may be available, we strongly recommend against running your own mail server in favour of using a dedicated email deliverability platform.

Hope that helps!
