Server 'mag2.properhost.net' blacklisted

To all customers on 'mag2':

Some of you may already have experienced issues lately where email is not delivery to Hotmail, Yahoo, or other addresses. We just became aware that the IP block which includes the main IP of our server has been blacklisted in the Spamhaus Block List (SBL). The domain that the SPAM messages originated from does not belong to any of our clients, as we have systems in place to prevent abuse of our services. However, the domain belongs to another customer hosted at the same data center as ours. Unfortunately, the IP address of our server belongs to the same IP block as the offending domain's IP.

We have already contacted our data center, and requested them to contact Spamhaus for removal from the blacklist. We have requested top priority for this matter.

We understand how frustrating this can be, however, there is nothing we can do to speed up the process. Hopefully it won't take to long before the listing has been removed.

Thank you for your patience.
