The discourse-doctor mail test failed with “Connection reset by peer” when using SMTP port 465 with Hover’s mail server. itsbhanusharma suggested trying port 587 instead, noting that 465 may require additional configuration.

Installed a fresh copy in a Digital Ocean droplet, everything goes through fine until creating an admin account which never gets sent. I’ve looked through the troubleshooting topic and tried several option, even the telnet goes through no problem. When performing the doctor checkup I receive the following

Have you tried a different port (e.g. 587)

465 needs additional configuration depending upon how the SMTPS server is set up.

Changing to that port (587) did the trick, thank you.
