I got a message from a user that our exim apparently sends a wrong status
code on full mailboxes.

Something like this:

550 Mailbox is full
550 5.1.1 [email protected]… User unknown

That's two separate responses.  The client much have sent
a subsequent SMTP command.  Without knowing what that was
it's hard to comment.

Some MTAs interpret the "missing" enhanced status code from exim and set a
default (eg. sendmail, exchange IIRC). So every 550 without x.y.z gets a
"user unknown" or something odd then.
