Thanks for offering your knowledge! I successfully set up and instance using their docker installation guide. However I was never able to get the smtp server to work. I first tried to add postfix to the docker-compose file like they have in the ansible installation example on github, but that didn't work. Just trying to add an email address to my account would stall the UI with a spinning animation on the Save button. I then tried to update the hjson config file by adding my sendgrid api credentials and removing postfix from docker compose. That gave me the same result. At that point I kinda gave up and deleted my vps. I don't have access to my error logs anymore, but I can spin up a new vps to try to get the same errors again if needed.
A lot of VPS providers block port 25 (and other email ports) because they don't want people to set up bot spam mail servers on their services. Could that be the issue?
I'm using a VPS with Hetzner. I'll have to look up if it's blocked. Thanks for the info.
I'm in the same boat and confirm that yes, port 25 is blocked.
