That's not a bad idea. Allbut the original harvester will not have that
information - assuming most lists are sold/shared sans original content.
As you say, it relies on MUAs faithfully reproducing References. Fortunately
for us .qmail types, mess822 provides reliable access to header fields
for those who want to implement that idea.
Spammers tend not to use the Subject line either, so a little pattern
matching would catch that. Though why spammers tend not to use harvested
subject lines is beyond me - i think it'd work a lot better than "MAKE
MONEY FAST".

Yep. That'd be a pain as you have to change on something like a weekly,
rotation.

Well heck pardner, round this neck of the woods some people might see
them as fightin' words! If you'd said use djbdns, then, well, yes,
we'd understand :>
