Email sender does not match notification email and I can't figure out why

Thanks very much!

@RGJ

The Sender: is something different. The error you’re getting indicates a discrepancy between the “envelope” (RFC821 From address) and the “From:” header (RFC822)

I was afraid of that. I’m much less familiar with RFC822 than I was 30 years ago. I know that "From " and "From: " and "Sender: " are all things, but not much more than that anymore.

@RGJ

I suspect that emailit (or maybe Discourse, we’ve been rolling our own mail servers for too long) is setting the envelope sender to the email address you’re authenticating with.

Maybe this will be the year that I do that. Email seemed much easier when I had to port Sendmail and UUCP to linux than it does now.

@RGJ

I think (!) you should make sure that notification_email and DISCOURSE_SMTP_USER_NAME are the same for emailit.

Seemed promising. No joy. Interestingly, emailit says that the SMTP_USER_NAME should be “emailit”.

But again, the SMTP stuff (including notification_emai) in app.yml worked just fine on this very same server with an empty database and stops when the database is restored.
