I'd appreciate it if someone at Microsoft could get both mail.grapheneos.org IPv4 addresses removed from the SNDS spam list:
51.161.8.140 (static IP of the server)
51.222.17.218 (newly assigned floating IP so we can avoid dealing with this in the future by moving it around)

No issues with any other providers because our server has never sent any spam and we've owned 51.161.8.140 for a while now. Microsoft's SNDS must have the IP blocks as a whole listed.
Standard contact form for getting this fixed hasn't worked. Not even an automated response.

Should have assigned a floating IP earlier so we didn't end up in this situation when we migrated to a new server instance for the mail server.
Got the new IPs removed from other blacklists before switching to them but Microsoft's form for this doesn't appear to do anything...

Didn't used to have this issue but the new IPv4 address of the server started out with the issue. I could swap the mail server with one of the other server instances to give it a new IPv4 address that's not banned.
However, I bought a floating IPv4 that I want to get unbanned...
