I think I'm having a similar problem, where I get spam via a mailinglist, and bayes gives the spam credit for having similar headers to the ham which arrives on the list. I'm not so concerned about including the headers as they arrive at the list server, but all the headers added from receipt by the list server seem inappropriate. I'll try bayes_ignore_header.
