Cannot get SpamHause blocklist to work. Exchange 2019 on-premise

Having installed the Exchange Antispam agents and configured the SpamHaus block list provider, I found that I was still getting just as much spam. I ran the SpamHaus blocklist test utilities and it is failing 2 of the tests - BLT Public SMTP Test Email (1557:20621:dbl-pub-ehlo) and BLT Public Content Test Email (1557:20623:sbl-pub-body-ip).

I have enabled everything on the ansispam agents and really now don't have a clue as to how to fix this problem. The articles pointed in in the emails are not much help to me.

Here are the email contents. Any help to fix this would be appreciated.


"This is a Spamhaus BLT public content-test email which has been crafted to be flagged as spam by properly configured mail systems. If your MX is correctly configured to do content filtering for the sbl-pub-body-ip test, then this email should be flagged as spam (check the
headers) or rejected outright. If this email was delivered, and not classified as spam, then your MX is not correctly configured for the sbl-pub-body-ip test; please see the BLT documentation at https://blt.spamhaus.com/docs for tips on configuring your MX.

Thanks Kimputer, the examples I looked at did not show those additional parameters. That has cleared 2 of the errors for me. I'll read through that documentation and see if it says how to reject the BLT Public Content Test which is getting to my inbox.

Thanks, that was a great help
