Why connection filter is not rejecting an email even when the IP is in the IP block-list?
Hi All, I added a blacklisted IP in the IP block list of the connection filter a few months ago. But the spammer can still send Malware from that IP. The IP is a Connecting IP Address...
I think I am getting to understand why something like this is happening:
This is my hypothesis:
The rules/policies and settings created using old Microsoft admin portal were not properly migrated by Microsoft when new security and protection portals were created.
What I mean is the older values in the IP Block-list for some reason are not read by the new connection-filter engine.

I also encountered another issue with editing the ASF settings of an anti-spam policy created few years ago.
For one of the old anti-spam policies and the default policy, I was unable to edit the Bulk email threshold (BCL) value . A slider to increase and decrease the BCL score was not present for these policies.
I created a new policy to test if I could see the BCL slider, unsurprisingly I could see the slider.
This means Microsoft had probably made some mistakes when migrating the policy settings/values from the old admin portal to the new ones.
Only Microsoft Security team can confirm this.
