A particularly effective anti-spam tool that I've see in use is to block mail claiming to be from a webmail provider (e.g. hotmail) that never actually passed through a server controlled by that webmail provider. Has anybody written such a filter for exim that can be run system-wide? I want to do it in exim because I don't have a global procmail filter in place and would rather not introduce one if I can get away with it.
Thanks. noah -- _______________________________________________________ | Web: http://web.morgul.net/~frodo/ | PGP Public Key: http://web.morgul.net/~frodo/mail.html
