it might be better to go by List-ID and be extra careful when Resent-*
are found.

Perhaps -- but then you have to work out of the Resent-* were before or
after the list, and you have to assume that the resender is
RFC-compliant and does actually _add_ Resent-* header. And you have to
assume that the headers won't get mangled in transit.

Filtering on the reverse-path is _so_ much more reliable except on the
rare occasion that it changes for an active list. Thanks for the regex.

The other only slightly less reliable alternative is to use the Sender:
header, but that's one of those things which only becomes apparent after
the morning's first cup of coffee :)
