Update March 12 – Microsoft’s block list is unfortunately automated and there is not a support line to reach out to. As soon as it detects a decrease in the volume of spam e-mail it will remove the block automatically. This is an unfortunate consequence of large e-mail providers.
In the meantime, I am continuing to audit domain names and reaching out to clients that have potentially compromised addresses. My own monitoring shows no substantial volume of spam sending from the mail server and only 1 confirmed account has been identified so far (and fixed). It’s mostly a waiting game at this point. Apologies for the inconvenience and thank you for your patience.
