Not a bug Automated bounced and unsubscribe email handler errors - authorization problems (cross post from community forums)

Affected version


Crossposting so I can get some official eyeballs on this:

I have set up a new XenForo forums, and have set up outbound SMTP through my email system that I control.

I am now trying top set up the Automated bounced and unsubscribe email handlers, and and am getting Auth errors. I have tried IMAP TLS, IMAP (non encrypted) as well as POP3 non-encrypted and all of them are giving me authentication errors.

I know that my email server works, and I have successfully tested the accounts using macOS (so I know I set the password correctly and IMAP is working fine).

Is there any extra debugging we can set on the client side (XenForo) to see a bit more about what is going on? On my server side, I get simple errors pointing to authentication:

Examples (redacted IPs and domain), one with pop3 and one with IMAP:

Jun 1 23:55:30 b6dbdf4fde68 dovecot: imap-login: Aborted login (auth failed, 1 attempts in 0 secs): user=<>,, lip=yyy.yyy.yyy.yyy
Jun 2 06:57:54 b6dbdf4fde68 dovecot: pop3-login: Aborted login (auth failed, 1 attempts in 0 secs): user=<>,, lip=yyy.yyy.yyy.yyy
Here is what is showing up in the XenForo logs in the WebUI:

As you already have a thread about this, a bug report probably isn't necessary. At first glance, this is unlikely to be a bug and is more likely to be a configuration issue.

If you require an official response, the best avenue to do that is to submit a ticket but given what I've noted about the likely culprit, we're unlikely to be able to provide support for specific server configuration issues.


Thanks for the quick response. I just didn't know if a Troubleshooting forum issue got official eyes on this. I'm new to XenForo (despite having signed up for the beta over 10 years ago!), and I'll open a ticket.
