RBL Blacklist behaviour?

Kevin Boyle
 

This is one of the SMG monitoring gadgets I created a month ago.

This is my filter

For quite some time now I was getting very few hits on my RBL filters then today I noticed an exceptionally large number of messages being blocked. Of course, I have made no changes to my system. :-)

Has anyone else noticed similar behaviour?

    The Spamhouse project since 2019 has made some profound changes in return codes that has led to problems with some spam solutions and filters. RBL from Spamhouse I currently use very reluctant because I have in the field again and again the issue of massive blocking of mail and that partly also domain are entered on blacklists of Spamhouse.
    Another issue is the question which DNS forwarders are used in the local spam protection mechanisms. I also often see problems that can be traced back to DNS resolution.
