I’ve recently looked into running a Mail server on Fly, using GitHub - docker-mailserver/docker-mailserver: Production-ready fullstack but simple mail server (SMTP, IMAP, LDAP, Antispam, Antivirus, etc.) running inside a container.. Currently the required ports 143, 587 and 993 would not be allowed (25 is). Could this be changed as well?
We aren’t adding more ports by hand (it’s more complicated than it should be). Enabling pretty much any port is on our roadmap, but we haven’t started work on it yet. It’s pretty important, though, so I’d really like to get it done.
I hope this comes next year. I have several applications waiting on port numbers to be chef kiss on fly.
No promises, but “allow almost any port” is near the top of our priority list.
