Sorry, but it doesn't look that way:
# bogoutil -p -w .bogofilter barrygould pennysaverusa.net
                        spam    good  Gra prob  Rob prob
barrygould              251   13047  0.056194  0.057041
pennysaverusa.net      1780   85259  0.060692  0.060819

'barrygould' I can understand: most of our spam goes to other addresses.
I'm not so sure about pennysaverusa.net, as all mail should say
"Received: from (server) by mail.pennysaverusa.net" ...

Regardless, I don't think it's a good idea.
It would pollute the db with other headers, like MUA=Eudora would start 
appearing spammy, even though it shouldn't be, esp as all my friends and 
family and many co-workers use Eudora.
It would also mess up the block-on-subnets data.

I can conceive that a possible alternative would be to forward messages 
with some sort of delimiter line telling bogofilter (or procmail) to ignore 
everything up to that line, but it would have to be defined by the user, 
otherwise spammers could put that line at the end of all spam :)
