https://sr.ht has recently been deployed to general availability. It seems like a Phabricator like tool in that it has many different aspects. git, CI, mailing list management, wiki, etc.

Yep! I am on a Lightsail instance and simply needed to open up port 25 for traffic. Thanks!

I'm trying to use the built-in email feature. I am hosting my Cloudron on AWS and filled out the appropriate forms. I have all check marks down the email page and am able to send email from my Cloudron account just fine, but when I try to email my Cloudron account, I get a 'Mail delivery failed' message a few days later. Has anyone had something similar happen?
