I've seen these headers, too; but it wouldn't a good mail filter to honor 
alien headers, would it? Unless you coded it, MIMEDefang has no interest 
in these headers.

I suppose those headers are there to trick MUAs, that are configured to 
normally be used in conjunction with a filter, that tags mail, and a 
second one that does not. Consider somebody who pulls private mail from 
some provider and bussiness mail from the firm's server. If latter is 
running anti-spam ware and tags the mails, but the provider does not.
