What you lose by using procmail or other separate delivery agent instead
of an Exim filter, either as an individual or using a system filter, is
the retention of handling a single message. Once Exim passes it to
procmail, Exim has "delivered" it. Consequently, if procmail wants to
forward it anywhere else, it has to resubmit it as a new message.
Whether this actually matters to you or not depends entirely on your
requirements. From a system filter, procmail can be run as a trusted
user, so it can resubmit messages with the original sender still intact.
An ordinary user using procmail cannot do this (unless procmail is
setuid).
