depends on your stuff: if you want to classify your mail, other than 
spam/good, you *may* want to keep just to: cc: subject: and body,
since you're mostly interested in the actual body contents.

But for spam/good extensive tests have shown that headers play a big role,
though how useful such role is, depends on classifier (eg ifile(1) didn't 
like them).
I'm used to trash all ID headers and zero date fields though, as that's 
pure noise.

See attached awk script to get an(other) idea to play with.
(you may want to (try to) re-implement it in crm as an exercise ;)
 if so pls post back :) )
