	That sounds like a bogofilter question, which you should be using 
bogofilter resources to try to answer -- like their mailing lists, 
newsgroups, etc....  I doubt that the Mailman-users mailing list is 
going to be very useful in trying to answer bogofilter questions.

	That said, if you want to keep from having your own address 
spoofed, I imagine you could add some bogofilter rules that look 
through the headers and increase or decrease the score depending on 
whether it appears that the message is originating from your machine 
and claims to have your address on it, or if the message originates 
from somewhere else but has your address.
