I’ve been self-hosting Discourse for many years, and had several instances happily configured and running on a fairly beefy machine. Today I noticed that one of my forums had gone down. The initial culprit looked to be lack of disk space, which I fixed. I then restarted the Discourse instance. How…

Yes that’s right, it’s the same problem … it started about two weeks ago.

Can you try both DISCOURSE_SMTP_ENABLE_START_TLS: false DISCOURSE_SMTP_OPENSSL_VERIFY_MODE: none ?

Bump, @pfaffman and/or @codinghorror . Do you think we may have a bug here, or something else?
