Hello Discourse Support/Community, I have been struggling for several days to resolve an issue with outgoing emails from my Discourse instance. I am running Discourse in a Docker container on a Spaceship VPS (Phoenix, US). My mail provider is Spacemail (SMTP). Issue: Discourse cannot send email…

Can you confirm you followed the official install ?

Yes, I followed the official Discourse installation guide for Docker. If you need, I can provide details about my setup or any adjustments I had to make for my VPS environment.

Error log details: When attempting to send emails from Discourse, I consistently receive a timeout error in the job logs: Job exception: Net::ReadTimeout net-protocol-0.2.2/lib/net/protocol.rb:229:in `rbuf_fill' net-protocol-0.2.2/lib/net/protocol.rb:199:in `readuntil' net-protocol-0.2.2/lib/net/p…

Try ports 587 or 2525 (try 587 first), do those work? 587 is the port mentioned in the install guide .

Thank you for your suggestion. My mailbox provider (Spacemail) officially supports only port 465 with SSL for SMTP. However, I have also tested port 587 with STARTTLS as part of troubleshooting (together with support), but the timeout issue still persists.
