Periodically, Microsoft (outlook.com, hotmail.com, live.com, msn.com and related domains) blocks our mail server. We have repeatedly explained that our server has never sent spam and is fully compliant with modern mail standards. We have correct SPF, DMARC, DKIM, and DNS PTR records. We are not listed—and have never been listed—on any public email blacklist.
This is Microsoft's response to our request for removal.
We have completed reviewing the IP(s) you submitted. The following table contains the results of our investigation.
Not qualified for mitigation.
108.174.193.29 - 108.174.193.29
Our investigation has determined that the above IP(s) do not qualify for mitigation.
II am done fighting this. Going forward I will ignore all email from the following:
outlook.com
hotmail.com
live.com
msn.com
hotmail.co.uk (and other country variants of the above)
any domain hosted on Microsoft 365
If your email address is on any of those domains, you will not receive email from Stovebolt. Microsoft has blocked us. You can either change email providers or accept that you will not get notifications, private message, or replies from the forum.
This message will remain Global for three days. It will also be a Sticky Thread in the Announcements forum. Moderators, please keep this in mind when dealing with questions about email not being received.
