I lied. I actually wrote a rule and stuck it in my testing area. As
always, don't forget to adjust the wrapping and lint your rules before
going live.
rawbody __CCM_UNSUB
/"https?:..visitor\.constantcontact.com\/[^<>]{60,200}>SafeUnsubscribe</
meta KHOP_CONSTANTCONTACT __CCM_UNSUB && RCVD_IN_HOSTKARMA_W
describe KHOP_CONSTANTCONTACT Remove DNS WL blessing for spam relayer
score KHOP_CONSTANTCONTACT 2.5 # combat dns whitelists
All this does is un-do the negative points HOSTKARMA_W assigns
(rather, the 2.1 points it assigns as implemented in my khop-bl
channel ... ymmv).
If you're not checking against a whitelist to undo it but rather
trying to block outright, I'd use something more like this:
header __CCM_RELAY X-Spam-Relays-Untrusted =~
/^[^\]]+ rdns=ccm\d\d\.constantcontact\.com\s/
rawbody __CCM_UNSUB
/"https?:..visitor\.constantcontact.com\/[^<>]{60,200}>SafeUnsubscribe</
meta KHOP_CONSTANTCONTACT __CCM_UNSUB && __CCM_RELAY
describe KHOP_CONSTANTCONTACT Constant Contact is a known spammer
score KHOP_CONSTANTCONTACT 4 # increase as needed
