Urk, how long would that take? What about one of those _really_ long
messages were some dipstick quotes an entire 100kb digest, adds a 250kb
code 'snippet' and dear ol'M$ s/w adds it all again in html plus one of
those '.vcf' thingies? Would hashing the message's header be plausible?
Is there any identifier that the pop/imap server one gets the message
from can be persuaded to provide?
