Can't send emails to external servers.

Posted April 26, 2014

Hi all,

I followed the iRedMailServer tutorial: (https://www.digitalocean.com/community/articles/how-to-install-iredmail-on-ubuntu-12-04-x64).

I can receive emails from anywhere but I can only send them in my local network (even between different domains). After dealing with a lot of issues, I’m locked on a connection timed out issue. From the log: connect to alt2.gmail-smtp-in.l.google.com[173.194.64.27]:25: Connection timed out

In short, I can’t connect to any external server using the 25 port.

Any help will be appreciated.

In some cases DigitalOcean blocks port 25 to help prevent abuse. Open a ticket and ask them to unblock it.
