Subject: Re: formail -D & using hashcodes instead?
Of course the checksum would be done only on the body. I think
either "sum" or "crc" (crc comes with zmodem) would write a good checksum
with them writing 16 and 32 bit checksums respectively. "crc" is:
I would suggest to use MD5 for the hash calculations. Otherwise, you
could get false positives.
In any event, only the message body should be hashed. Headers are too
dependant on the delivery route (and off course, the Message ID would be
different).

"I hadn't had any psychedelic drugs for almost ten years since the '60s
when we were all loonies, so I thought maybe I should have it to just
see... if it reminds me of anything... You have to be careful (with
mushrooms) because they're so good. That stuff is very organic, you know.
You feel great, and everything is in perfect focus, even the physical body
feels good. But because I felt so good, I kept on eating them all day. I
nearly did myself in; I had too many. I fell over and left my body, hit my
head on a piece of concrete - but they were great!"
