We thought about doing this way too, but how do you handle the same
email routed to 2 different local users that has different system filters?
AFAIUI, the system filters are executed just once per delivery
(different from user filters that are executed at each mail routing) so
we are feared that just the system filters of a user (random? the first
rcpt to?) is used instead of the system filters for each user mail routing.
Thanks in advance,
