Allow splitting a message copy to a connector
As far as I'm aware, one can use a filter to redirect incoming mail to a certain connector, but one can not redirect a copy of mail to that connector while leaving the original delivery path unaltered. It would be very handy.
Adding a Bcc is an alternative, but it suffers two flaws: one cannot specify an IP address as a destination, and one loses the envelope information (rcpt-to) in the process.
And just to add to this -- we want to do this fro archiving to our internal server. Journaling is one method, but it also can only deliver to a deliverable address, and not an IP. Adding this functionality there would be great as well.
