Your mailer daemon keeps blocking my servers emails. We have DKIM, SPF, everything in place but you guys will not unblock us. I've tried using your self service tool to unblock our address/ip but it does not work. I've tried sending multiple emails to the mailer daemon email that it lists, but nobody contacts me back. This is becoming an issue for clients that pay us for email. Please contact me.

    Hi @Chris Alvis

    Use this tool to see if you are on the blacklist.

    https://sender.office.com/

    You can use the same tool to apply for your IP to be removed from the list.

    Reason you're block is because microsoft blocks whole ISP IP ranges at a time when spamming is detected.

    Let me know how you get on.
