Just started getting these today. Looks like one of my colo neighbors
behaved badly. No useful info at the suggested link, no contact
given. Any suggestions on how to get my address unblocked?

As far as I've ever been able to tell, S3150 means "Our Pseudo-AI thinks
you stink!" and the way out is to find the link on that page for senders
with problems, jump through the hoops, respond to any requests for
info, and eventually get a reply from "Hotmail Sender Support" using the
magic phrase "not eligible for mitigation." This incantation does not
mean what it seems. It is actually a signal that you have reached the
point where you can get a solution (usually?) by replying with the magic
phrase "PLEASE ESCALATE THIS TO SOMEONE WHO CAN ACTUALLY ASSIST ME"
which may or may not need to be in all caps.
At this point, you may need to wait up to a day for a response. It
probably is advantageous if you have an existing SNDS & JMRP account and
if in getting to that point you've provided a true AND plausible story
of what sort of mail you send and its volume. If your pleas convince the
MS Gnomes of your virtue, you will be "mitigated."
This may sound like I'm joking, but I am not. Even when working both
ends of the sender/receiver relationship (as we manage customers' MS365
environments as well as running mail systems for customers) the reasons
for blockage, failure to get results at the first level, and ultimate
success are opaque. They may as well be magic. I have had success with
this multiple times over he past few years, but many others here and in
other fora seem not to have been as fortunate. No one has ever claimed
to have an explanation for why a S3150 blockage happens or what exactly
the 'mitigation' consists of.
