Is DNS Blacklisting working?

Postby momzeycom » Wed Oct 25, 2017 4:08 pm

How can I verify that DNS Blacklisting works.

I selected all 3 dns blacklists for both DNS Blacklists and URL Blacklists and Action when detected set "Mark the email as spam"

I am assuming I should be receiving some email marked as spam and I am not.

Hi,

When a message is marked as spam by the reverse DNS blacklisting action it will be delivered to the users junk email folder and will contain a header in the message as: X-ME-Content: Deliver-To=Junk. If the message does not contain the header then most likely the message body did not contain a URL present in a blacklist or the connecting IP address was not found in a DNS blacklist. Check the SMTP log files as it will log blacklists checks in the debug log file.

You can also add a "Response" record to the log file to help locate blacklisted IPs.
