Followed the instructions here: https://www.digitalocean.com/community/articles/how-to-install-iredmail-on-ubuntu-12-04-x64
I can receive e-mail but when I try sending e-mail to any address (tried gmail, icloud, etc) the logs show something like this: “connect to alt3.gmail-smtp-in.l.google.com[173.194.70.26]:25: Connection timed out”
If I try to telnet alt3.gmail-smtp-in.l.google.com It says “Trying 173.194.70.26…” and hangs.
My server is new, iRedMail is the only thing i’ve installed.

DigitalOcean, why don’t have transparency about server and network limitations? why don’t put a disclaimer in your tutorials about MAIL SERVERS?
Three days wasted on this issue too. Thanks, Digital Ocean.
There’s definitely a lack of transparency here, so, add me to that list.
I had this working for years on a server and all of a sudden without any announcement it was blocked/failed.
It’s also non-obvious and under-documented that it’s possible for IPv6 mail to be completely blocked even if IPv4 isn’t (so, even if you think you’re in the clear because things work where you tested, you can end up with periodic failures if you’re dealing with somewhere that has IPv6 mail servers in their DNS rotation like say Office365 or Gmail).
