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)

An alternative is that I could keep buying floating IPv4 addresses from OVH until they give me one Microsoft hasn't blacklisted. It's not that expensive but I find the concept ridiculous. I should probably just do this so attestation.app alert emails work for those users.

If we switch to a new sending IP address, it's possible it will be blacklisted elsewhere. It's ridiculous since they've never received spam emails from our domains and we have DNSSEC + enforcing DMARC so they can see it's from us. It should bypass a blacklisted IPv4 address.

A temporary workaround would be swapping the mail server with one of our web servers without a blacklisted IPv4 address. I want a long-term solution though which means having a floating IPv4 address that's not blacklisted, which means playing the lottery ordering more of those...
