I was asking the same thing a few days ago and kinda came to the
conclusion you can do such a thing in the system filter with soemthing
like this:
if "${lookup{$h_received:} lsearch {/etc/exim/spammers}{spam}}" is "spam"
then save /usr/home/scott/mail/Z-Spam
seen finish
endif
The /etc/exim/spammers file is set up like this:
domain.com
spammer.net
weliketospamyou.net
etc....
I prefer to save the email in a catchall rule. I'm not sure if this is
working, as you must have a list of domains in the spammers file. I hope
the above is working, and would greatly appreciate any pointers.
Hopefully the filter looks in the Received: headers and tries to do a
match against domains listed in the spammers file.
