[exim] forward v bounce

We just sent out a message to our allumni mailing list, we had filters
for the bounce messages so they could be put in the list owners bounce
folder, that way the list can be pruned of duff addresses.

I was very surprised to find lots of bounce messages from AOL appear to
have been forwarded back to the person in the from: header. Thus not
appearing as a bounce message at all and not getting filtered.

Is this common practice?
