ATT blocking emails from OptiBoard

Just a note to let you know that ever since the server move ATT has been blocking all emails from OptiBoard. This probably has something to do with a previous owner of the new IP address we have. We have asked them to remove this block, however they have refused to respond or comply with this request so far.

If you have any of the following email address domains, then you may either want to contact your provider and ask them to remove this block, or change your email address.

att.net
swbell.net
prodigy.net
bellsouth.net

Note: If you are registered on OptiBoard and have one of those email domains, then you will not receive any emails or notices from OptiBoard until ATT resolves this.
