Forum SMTPAuthenticationError

We are getting the following error in the logs.

Jobs::HandledExceptionWrapper: Wrapped Net::SMTPAuthenticationError: 535 Authentication failed

Looks like an SMTP authentication error w/ Mailgun. There are > 18k failed attempts. I’m traveling today and can look into this more closely tonight.

I probably need to reset the SMTP password in mailgun and update the .yml file and rebuild discourse. that will result in a 30 second outage. I will just do it when ready hopefully later tonight.

CPU is spiking to process the email backlog. it’s possible users will get a LOT of email when I fix this.

I just dumped the email backlog. Taking a snapshot and will rebuild shortly.

Looks like this rebuild fixed the SMTP issue. Everyone should be receiving emails from the forum now.
