I guess Microsoft tend to block whole networks if they see something
they don't like, so it's not necessarily your mail server but
something else in the neighbourhood responsible for the block.

I recently managed to get my mail server unblocked (virtual machine
with single IP address in some dodgy network neighbourhood) via their
support form by showing that I only have control over that single IP
address and anything else is outside of my control.

Hmm, probably not. That one seems to be outdated.

It says
"Please note that IPv6 is not currently supported".

Is it really the right one?

it looks to me they’re really telling you to talk to your upstream (Internap if 
I read the whois for 66.151.17.22 correctly.

As is par for the course. It is the natural default assumption that the problem 
is caused elsewhere.

FWIW, the last interaction I had with the powers that be at Microsoft over a 
related manner, it took a few days after I had published a blog article 
(https://bsdly.blogspot.com/2018/02/a-life-lesson-in-mishandling-smtp.html 
) 
before any visible reaction from their end.

[mailop] Microsoft blocking/spammarking messages

[Nate Burke via mailop]

Hello, I was hoping someone from Microsoft could contact me offlist for 
help getting our server (66.151.17.22) removed from the Microsoft 
blacklist.  I'm having problems sending to outlook.com/msn.com and 
others with domains hosted at office365.  I can't find any issues with 
the server, and I don't appear to be on any other blacklists, but all 
messages to Microsoft are either getting rejected or sent to the spam 
folder.  The mailserver has been at this IP for many many years, but 
these issues just started about 10 days ago.


Any help would be appreciated.

Error message;

<<< 550 5.7.1 Unfortunately, messages from [66.151.17.22] weren't sent. 
Please contact your Internet service provider since part of their 
network is on our block list (S3150). You can also refer your provider 
to http://mail.live.com/mail/troubleshooting.aspx#errors. 
[BN8NAM12FT057.eop-nam12.prod.protection.outlook.com]


The link does not appear to have any way for admins to view/remove the 
server from the blacklist.
