True, but there is at least one MUA - TBIRD that behaves this way. I
have not used Outlook in a long time to recall if it had similar
behavior. I will lean to the side that it did because its quite
possible the latter designed TBIRD researched and borrowed the logic
or probably felt it would be easier design for this human usage to
make the correction than to try to behave like a real MTA with
redundant retries. Although, there is the design option it could
issue a prompt:
"Do you wish to add the temporary rejected recipient in the
CC list into your 'Send Later Folder'?"
It wouldn't work well for automated backend MTAs.
