My experience is that MS uses its own system and I do typically, not
always, find my server on other RBLs when I'm on MS. Currently I'm
having issue with Cisco's Talos system even though I'm not on any from
https://multirbl.valli.org or MSToolbox.
This is where I deal with MS if you haven't seen it before.

Hi,
Just over two weeks since I found myself on Microsoft's blocklist and
was manually removed, I find myself back on their blocklist again.
Possibly coincidentally, this morning MXToolbox informed me that
Linode has apparently found itself back on Uceprotectl3. Does anyone
know if Microsoft considers that particular blacklist when deciding to
blocklist an IP? Naturally, I've submitted a deliverability support
ticket, and will probably have to wait several hours for the result.
As always, I'm not doing anything wrong (that I know of at least).
Even if someone had hacked my server, my hypothesis is that they'd
have to be a very careful and methodical hacker if their aim were to
get me blocklisted by Microsoft and only Microsoft. If my server were
spewing out spam, I ought to be hitting Spamhaus/SORBS/etc. spam traps
left and right. Trust me, one time I was hacked, my server was sending
out spam and I didn't know it, and I quickly found myself on Spamhaus
XBL.
Any thoughts?
Thanks,
Jayson
