Bayes: Is mail without headers better than no mail at all?

[jonathan soong <jo...@imvs.sa.gov.au>]

Hello..

I am currently in the process of implementing a site-wide Bayes database.

I understand the difficulty in processing forwarded mails (explained in 
the Wiki).

I was wondering tho, if i create two accounts (spam/ham) and just have 
users FORWARD mail to these accounts, could i still use this mail?

Obviously the headers are likely to be stuffed, but what if i strip ALL 
headers and just feed the body of the mail to sa-learn. Is this better 
than nothing, or will my Bayes db end up skewed as it has been 
header-deprived?

Any opinions most appreciated,

Cheers

Jon
