Outlook blocking all email - "email harvesting"
I've got a plan with Hawkhost on a VPS server for our community, subscriber only, trade and announcements email list.
Outlook has completely blocked us so I've recently gotten messages from mailman bounces that about 400 of our subscribers (all the hotmail, live, outlook, etc. users) have been disabled.
I have signed up with the SNDS program and it reports that email is blocked because we are "email harvesting". (I am working with Hawkhost on a trouble ticket). I've tried to sign up with the JMRP program as well but when I click the link I get sent back to the SNDS page and cannot figure out how to get out of that loop to get actual user feedback complaint reports, if any. But that is a different issue.
I am hoping you folks can shed some light on what to look for.

Dear James Dory
We have completed reviewing the IP(s) you submitted. The following table contains the results of our investigation.
More information needed 198.252.110.38 There are indications that the above IP(s) are engaged in namespace mining. Outlook.com is blocking all email sent from this IP.
Namespace mining is a method commonly used by malicious senders to generate lists of email addresses. This approach uses automation to sift through possible email names seeking to identify valid email addresses, e.g., Joe@domain.com, John@domain.com, and Josy@domain.com.
You must correct the problem and you must stop the behavior described above. We recommend that you work with your email or network administrator to review the logs of your email servers. Check the sending log files and concentrate on logs that are sending to nonexistent @hotmail.com, @live.com, @msn.com, @outlook.com?with http://outlook.com/?with multiple tries and failures.

I'm not sure what you're asking. Microsoft is blocking your IP for stated reasons. These reasons may or may not be valid, but this has to be addressed with Microsoft in any case. In my experience (none too recent) this is a difficult, tedious process and is sometimes futile.
Out FAQ article at https://wiki.list.org/x/4030690 has a link to https://mail.live.com/mail/troubleshooting.aspx. This has some good info. Unfortunately, the link to set up a JMRP[1] account seems broken, but buried in the "Sender services, tools, and issue submission:" section is a link to contact support which seems to work.
Here again, my experience contacting support is it takes multiple back and forth messages (all of theirs seem like they could be generated by robots or at least copy/paste from canned replies) and you never get a real answer, but eventually the block gets removed.
[1] I don't think JMRP will help anyway. JMRP has to to with complaints, i.e. recipients clicking spam or junk buttons, and the reason they give for blocking you seems more to do with the patterns of addresses you are trying to deliver to. Also, it's possible that they are blocking a larger netblock and your (innocent) IP just happens to fall in that range.
