Subject: Re: [Exim] Bogofilter and Exim
A couple of things here

What prevents a spammer from adding a x-bogosity header that makes it
look as if it is not spam? Or if someone forgot to put

domain = +local_domains

in the router and sent filtered and thus x-bogosity headered mail out?


- bogofilter replaces the x-bogosity header with the -p switch.

Is there a simple way to remove the header on mail coming from the outside?
