...or *who had it before you did* (particularly for static or
not-so-dynamic dynamic IPs).

A spammer could have set up a "throwaway" server and blasted spam from
that IP until it got blacklisted, then moved on, leaving you to inherit an
IP with a bad reputation.

That may or may not be an easy problem to address. Potentially the
simplest solution is to ask your provider to assign you a different IP
address and hope that one isn't listed as well. You could proactively
spot-check IP addresses in the network block managed by your provider and
if a more than a few of them are listed (particularly by multiple DNSBLs)
then your provider is probably problematic and you should look elsewhere.

If you get a useful result it might be nice to summarize it to the list.

Agreed, it seems to be deliberate to get people moved over to the big
providers, they are clearly discouraging independent email servers as
they clearly scored differently.

I have even been doing tests on various spare unused ip's and the
amount that get blocked by microsoft (but no other providers) is
unreal.

Also to mention their own outlook software part of office, if I even
set low level filtering, it has insane levels of false positives.

By frustrating/sabotaging other providers services, they create an environment where users are forced to switch to the outlook.com/gmail.com cloud. Eg. what you have done is already more than gmail.com is doing, they are still working with an spf ~all.
