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.
