DNS - Forward Confirm Fail
Problem reported by kevind - Yesterday at 11:46 AM

Receiving a lot of spam today and noticed a particular issue. It's not getting scored by Reverse DNS - Forward Confirm Fail, even though it fails at MultiRBL.org.  Example:
Received: from blazaq.weehdcph.com (demo.srm-deals.x5.ru [85.118.130.83]) by "MyGateway" with SMTP;

X-SmarterMail-SpamAction: None | NoAction
X-SmarterMail-TotalSpamWeight: 6
Plugging the IP 85.118.130.83 into MultiRBL.org finds a Reverse DNS entry.  But it shows "No record found" for Forward Confirm. This test has worked in other situations. Am I missing something or have spammers find a way to get around this check? Thanks!

Maybe I already did full analysis and posted about this 7 months ago:

Not sure if it's the identical issue with CNAME, but still not working. I'm on a 2024 build. Has it been fixed in a newer build???
