Right; that's what MIMEDefang gets handed by Sendmail.

MIMEDefang's copy isn't really "in transport" unless you modify the
message body.  If you only alter headers, then the "in transport"
copy is whatever's in Sendmail's queue file.

I know of no good way to handle this.  I'm inclined to simply reject
messages with embedded CR's because MTAs sending such messages over
the wire are violating a MUST NOT requirement.
