Unable to send mails using Discourse

Support Self-hosting

AI-generated summary

User ceeaim is experiencing issues with sending emails using their Discourse installation, with both Zoho and Mandrillapp SMTP servers. The production logs show a “422 Unprocessable Entity” error, while the Sidekiq email error queue logs indicate a “Net::SMTPAuthenticationError” with the message “Error: authentication failed.” mpalmer and pfaffman both suggest that the issue is likely due to incorrect credentials (username and/or password).

There you are, then. Your credentials are wrong.

That is to say, there is something wrong with the username and /or password (or, perhaps the address/host name, but that’s pretty unlikely).
