Basically, I am facing the same issue as described here: [https://meta.discourse.org/t/job-exception-535-authentication-failed/172537](https://meta.discourse.org/t/job-exception-535-authentication-failed/172537)

For some reason our E-Mail outbound does not work anymore and I get now an error 535. I rechecked the E-Mail account. I can login there and use it from Apple Mail. SMTP Mail sending I also tested with Apple Mail. But discourse gives me this error message “ERROR – 535 auth failure”. I am not sure, how to proceed here. Is SMTP still supported?

My tests until now:

1. I tried different Mail Accounts
2. I tested the Mail Accounts with another Mail Software
3. I updated to the latest discourse version. (3.2.0.beta1-dev)

Any help would be appreciated.
