Hello That is a SMTP error message, which has nothing to do with SOGo.
It is a character outside ASCII, which is not allowed in email Headers, except it states UTF-8 usage in smtputf8.
But the used character is not an UTF-8 character either. Therefore it is an invalid email, so what do you expect? Kind regards, Christian MackAm 31.10.24 um 20:27 schrieb "Rick Bychowski" ([email protected]):
