Thanks for the clarification Brad. I had missed that concept. The crux
here seems to be that since subscribed addresses are ultimately going
to end up as envelope to addresses, they need to meet the requirements
that RFC 2821 places on the content of RCPT commands, namely they must
not contain non-ascii characters or ascii control characters.
