Hi,
Strange problem today : a particular email isn’t getting delivered into my mailbox. rspamd sees it and doesn’t classify it as spam.
What could be wrong ? For the record that’s the same server with which I had problems yesterday trying to configure a smarthost - may or may not be related.
The lines related to this mail in the maillog :
I see this : SMTPUTF8 is required, but was not offered by host mail.gaillet.be[
