Sent multiple test messages to my Cox email accounts (from outside Cox) and the messages are not being received. Noticed this because daily messages I get had not been received. Outgoing email works fine.
Oklahoma Cox user here, same issue. I haven't received any emails since sometime last night.
Yeah, I got my last incoming around 12:05 this morning (east coast time) and see that a text message I got on my phone at 05:00 has not been appropriately echoed via incoming email as it should be.
