Identified
Hello,
It has been reported that several Hosted ZixGateway customers are having AT&T block their IP addresses for emails going to AT&T-owned domains. Email destined for prodigy.net servers is being treated as SPAM and is actively being blocked.
We have taken the necessary actions to have this email traffic allowed through and currently awaiting AT&T decision.
