As mentioned above, I tried port 2525, rebuilt, and still no luck. DO claimed that ports 24, 465, and 587 were blocked/filtered, but said it wasn’t on their end and suggested I edit iptables -nvL. I don’t really understand iptables -nvL, and I tried my best. No change. So I just went off on DO in an email requesting again that they unblock those ports. We’ll see if they help at all.
Their ‘1-click’ Discourse install has been a nightmare. SSH key didn’t work (permissions denied) and when I went to edit permissions through their consul I was asked for a password (which they never sent me because I was using an SSH key I had uploaded to my DO account)! I ended up destroying that droplet and starting over following the 30-min guide on Git. But problem persists. I don’t understand why DO would default to blocking SMTP ports on a ‘1-click’ Discourse install when Discourse can’t function without an outgoing SMTP email. That seems soooooo stupid to me. Anyways… done with my rant.
Appreciate you taking the time. Adam
