Listserv-based spam

Postby Pentangle » Tue Mar 21, 2017 6:44 pm

Hi all,

I'm having a little trouble with one of my customers being targeted by listserv-based spam - i.e. he gets a shit-ton of it and the vast majority of it has "unsubscribe" in either the message body or headers, or "Feedback-ID" in the headers

However, when I use the following rules in custom_rules.cf it doesn't trigger on either of them:

header SPAM_MAILER_1 /Feedback-ID/i
score SPAM_MAILER_1 1.5
describe SPAM_MAILER_1 attempt to remove listserv-based spam
rawbody SPAM_MAILER_2 /Unsubscribe/i
score SPAM_MAILER_2 1.0
describe SPAM_MAILER_2 Mailing list bump up

Any idea why?
