Question

Why do Digital Ocean Block SMTP?

I’ve been trouble-shooting sending email from my application using Zoho. It works locally, and on another (non-DO) VPS, but after trying with Digital Ocean for a looooong time, I have found that they block SMTP connections in an attempt to stop spammers. The ability to send email is an absolutely crucial part of my web app (like any web app), so having this functionality disabled for 60 days in unacceptable.

Why don’t Digital Ocean tell people about this when they’re signing up?! It would have saved me many many wasted hours’ work.

Are you sure you don’t have an firewall that blocks the port? I have succefully implemented an mail server (postfix-dovecot) on DO and never noticed that DO blocks ports (would be strange).

agree this is unacceptable now i do moving all server to another services to leave DO

we have the same problem. more than 120 days and digital ocean does not unlock our emails we are spending a lot of time trying to find a solution but we know it’s blocked by digital ocean lately they are forcing us to look for another company I’ll open a call on the linode, they have good answers.
