Hello,
sorry for my bad English.
For spamfiltering I set the header "X-To-Whitelist" and "X-Blacklist". I
want a mail to be filterd if: both headers are yes, none of them or only
X-Blacklist.
So it would be like
A | (A & B) | (!A & !B)
= A | (!A & !B)
= A | !B
So I use the rule
* ^X-Blacklist: Yes | !^X-To-Whitelist: Yes
If I now receive a mail containing none of this both headers I get:
No match on "^X-Blacklist: Yes | !^X-To-Whitelist: Yes"
where is the mistake?
mfg
stefan
