It's a bad idea, but you could do it with a Milter. Extract the
recipient from the MTA-to-Milter SMFIC_RCPT command, and send that
in the Milter-to-MTA SMFIR_CHGFROM request. And do something sensible
if a message has more than one recipient.
The problem is that it changes the error reporting address in a way
that breaks error reporting; if m...@streamservice.nl has a delivery
error, mail will loop between m...@mynoc.eu and m...@streamservice.nl.
You might just as well specify the null sender in the SMFIR_CHGFROM
request, or add "NOTIFY=NEVER" to the SMFIR_CHGFROM request.
