Blacklisting on headers

Post by Chiny » Tue Oct 31, 2017 1:05 pm

Generally useful but getting urgent with MailChimp's recent change of opt-in policy, would be the ability to blacklist on headers. Immediately I'd blacklist anything with [X-header contains MailChimp] although some/most would need a whitelist for their genuine sign-up to MailChimp stuff.

Unless there is already a way...

Not a blacklist exactly, but what we can do is create a custom rule for SpamAssassin and then a score can be added for that.

(I apologize for the late response, we're supposed to get email notices when there's a new post.)

If you have some header samples readily available can you share them? I can dig through my email as well, but I don't have anything I know was from MailChimp off the top of my head.

No MailChimp spam at the moment. How about ccsend ? Another lot plaguing my Inbox at present. Perhaps I should be able to zap on X-CMAE headers (Cloudmark ?). Lots of potential X-headers to use.

I would have thought I could blacklist on sender:
Sender: Vendes <newsletter@vendes.ccsend.com>
but blacklisting ccsend.com fails.
