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 ?

Once I made sure to specify plaintext SMTP and port 25, I can send email via the host just fine: $ cd /var/discourse/ $ sudo ./launcher enter app x86_64 arch detected. root@discourse-app:/var/www/discourse# curl smtp:/…

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

@gunnar I moved your post here since this is the email issue you’re describing. I am not sure if the “post has already been taken” error is also being caused by this, but the details you gave about your email belong to this issue.
