hi Jay, thank for your reply.
I agree that discourse-doctor is not used for a healthy patient :slight_smile:

OK I tried again as per your request, and still the same error. And this is on a working discourse forum WITH working email (it mails users just fine).

Sending mail to [my email address]
Testing sending to [my email address] using [discourse mail address]:[password]@[mailserver]
