One technique I used for my own list software (now defunct) was that
every N'th message to each subscriber was sent individually with
custom headers giving the subscription address, list name etc.  All
the other sends (the rest of N) were sent as per normal with 100 RCPT
TO's per message.  Then, instead of attempting to parse bounce
formats, instead I merely looked for these custom headers in the bouce
returns and tracked that way.

In this way, by rotating the N thru the subscriber base so that on any
one particular posting only 1/N'th of the subscribers were sent
individual messages I could minimise mail load on the system and have
an guaranteed accurate tracking system for who was *really* bouncing
when there forwards inbetween.
