I don't have the precise general function mentioned above. I seem to
remember I raised the question of what do you do if "to:" contains more
than one address, each potentially requiring a different re-write? This
was what led to the point about another rewrite stage just prior to
delivery, and as a result, I *do* have on my list the following:
Option to set up a filter to process for deliveries via specific
transports. Pass message and address(es) to a command and read it
back. This gives the opportunity for encryption on the fly, and any
other address-specific munging.
I might even get round to implementing it.... :-)
