Hello!
I’m prettu new to discourse admin so please forgive me if I’m asking something already answered (I already searched for similar issues but did not foud a solution).
I configured our instance to deliver notification messages via authenticated SMTP: I tested it several times and it works; the notification email address is forum@HIDDEN.TLD
As soon as I configure the “reply by email” address to our chosen reply address - forumreply+%{reply_key}@HIDDEN - and set replay by email enabled
, all our email notifications and test messages stops to be accepted by our SMTP server whith this error message:
553 5.7.1 <forumreply+verp-8e9a1faf39a04faac9b5de75c5ea1f89@softwareworkers.it>: Sender address rejected: not owned by user forum@HIDDEN
I understand I cannot use forum+%{reply_key}@HIDDEN
since Notification email cannot be the same as reply by email
I’m not able to have a look at the source of the failing message, so I cannot check how email headers are configured.
Please: can someone confirm that the “reply by email” settings I did are fine? How can I have a look to the headers of the rejected emails, are they saved in some log file (I cannot find it)?
If the “reply by email” config is fine then I should check out why our SMTP server is rejecting legit outgonig email.
Thanks for any suggestion!
Best regards.
