Any emails going to .rr.com accounts (basically any RoadRunner accounts) may be delayed.
To be fair - other vendors (SalesForce.com) are getting the same delays.
GoDaddy Advanced support acknowledges email from their customers is being delayed but won't take any action, saying RR needs to lift restrictions. Of course, RR says GoDaddy needs to initiate. Neither will talk to the other....
The problem isn't a specific GD account. It's any email coming from GD email servers (secureserver.net).
I know this is a community forum, if you are having a similar problem tack onto the thread. I suspect most people don't realize there is an issue.
