I can't seem to find that either. If it was indeed removed can it be reinstated? Having this listed on the Manage tab right under IDS Blocks was perfect, you could see if there was a problem instantly every time you log in.

Hello everyone! Sorry to hear this is an issue for you, and your post lead us to find a missing release note on this change. This area was removed from SmarterMail as it was notoriously problematic and blacklists regularly update querying methods resulting in this area being non-functional at times. We're going to get a release note added on this for the future as well!

It was always pretty functional to us. Even if it can't check some spam lists for some reason, it was very helpful and it was better than having nothing. Specially it was good with spamhaus

It has always worked well for us too and we miss it!

The only note I would make: being able to configure the blacklists to check.

For example, we would like to disable UCEprotectL3 (which is SCAM...) and add 2-3 more.

Alternative, works great.  The verification of my ips arrives in my mail daily.

That makes sense and we do have a request in with our teams to evaluate the request to add it back in. I apologize for the inconvenience. To add to what Jack suggested, MXToolbox.com also offers daily monitoring services for blacklist status, deliverability issues, response times, etc. 

Add it back please +1
