Unfortunately at this time, AT&T forwarded mail continues to be blocked. We have been aware of the mail-blocking issue when forwarded to AT&T and their partner sites. easyDNS has submitted multiple and continued de-list requests. We continue to work on a resolution and hope for one very soon. Please feel free to contact AT&T with this concern as that may speed up the resolution of this problem.
Update: This has been resolved as email forwarding to AT&T is now working as expected.
