SMTPAuthenticationError: 535 Incorrect authentication data

Where would I find out how to handle all of the “ SMTPAuthenticationError: 535 Incorrect authentication data” errors that I’m seeing in my logs?

Apologies if this has been addressed before. I searched and didn’t find anything.

Is mail getting sent? Are there clues in the logs of the mail server?

All I can think of is Troubleshooting email on a new Discourse install

Yes. Mail still seems to be coming to my test accounts. Just not highly confident that other issues aren’t going on. I’ll check that out. Thank you.

if you dont come right, DM the details and i will log in and check out the settings,
