Hello. Thanks for your reply
in mail-receiver.yml I have base_image: discourse/mail-receiver:release and do not see an error message about the mail-receiver being old. I’ve rebuilt the mail-receiver many times.
I do not see any email as rejected here: /admin/email/rejected
I did issue a new API key for user system with all privileges. I’m using that in mail-receiver.yml. I was thinking the API was the issue, but I’ve check the numbers match a few times.
