Sorry if it seemed like I said that. It's either a potentially valid EAI message or a definitely invalid ASCII message. If your system doesn't handle EAI mail, it's invalid. If there are bytes with the high bit set but they're not a UTF-8 sequence, or they're not a UTF-8 character allowed in an authserv-id it's invalid even if you handle EAI.
