We are not at that volume, but we regularly (every 3-4 weeks) have been
having problems delivering to Microsoft products since about October.
Always comes back with this error.
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.
Of course that URL had no information about the S3150 block list, or any
other helpful info.
I was submitting a mail delivery problem request through their support
forms at
https://support.microsoft.com/en-us/supportrequestform/8ad563e3-288e-2a61-8122-3ba03d6b8d75
but those seem to not be working right now. Every previous submission
was replied to with 'no problems found' and the block would continue
for another day and then magically mail would start flowing again.

Hi there,
since yesterday I have experienced no mails getting through to
Microsoft (Office-365, hotmail etc.) and Verizon (yahoo, aol).
And since I ham having hundreds (or probably thousands) of undelivered
mails in the queues at all times since this started to happen I wonder
if I'm the only mail-operator around here who experiences the same
right now.
Also, their Support-Forms seem to be dysfunctional right now.
