Karl,

Good job in getting bogofilter working with your mailer :-)

It's not a problem.  In lexer.l is code to detect any "X-Bogosity" header 
lines and remove them.  Any attempts by a spammer to supply their own 
X-Bogosity lines to deceive bogofilter will fail.  Note:  you must be using 
the passthrough option ('-p')  to have bogofilter rewrite the 
message.  (The rewritten message has old X-Bogosity lines removed and the 
new one inserted at the end of the message header).
