Hi @aleemfirnas22

If your account with DigitalOcean is new, then all SMTP actions are blocked and you need to create a ticket with Support via the control panel and ask to un-block SMTP. This is to prevent SPAM.

Make sure you’re connecting with it over IPv4, not IPv6. It seems like DO is blocking IPv6 SMTP traffic.

And for what it’s worth, you can test by connecting with Gmail’s servers with the following: $ telnet 587

Then to test with IPv4: $ telnet -4 587

If you see it trying to connect (and failing) with IPv6 with the former command, but succeeding with IPv4 in the latter command, you’ll need make your droplet use IPv4.


How did it work on localhost? What tutorial did you follow?
