Tue Nov 4 19:04:49 UTC 2014 - We experienced problems with mail crossing authentication for customers relaying mail through the service. We are actively working to correct the problem.
Tue Nov 4 19:35:30 UTC 2014 - We discovered a problem on an ancillary system that indirectly affected authentication. The problem has been resolved and mail is flowing properly at this time.
Thank you for your patience as we resolved the issue.
