So how about this:

There's still the issue of wrapped fields, which you do see in To:
fields every now and then. The formail solution I proposed should work
fine in place of egrep, though.
(Yes, I know I didn't flesh out the -xOriginal-Resent-To:
-xOriginal-Resent-Cc: etc etc but should you care very much about
those? For catching spam, I'd just look at To: and Cc: and maybe the
presence of an empty Bcc: since some mailers leave them as a trace
that somebody has been Bcc:ed. Also X-Apparently-To: is a good one to
include, but that's about it, I think.)
