Over the last six (6) weeks we have had clients reporting that some of their emails are taking as long as ninety one (91) minutes.   All of the clients were using Verizon's mail system for outbound mail because Verizon is blocking port 25 (SMTP) .. we can if required have your mail server here listen on another port which will allow you around the Verizon block, and allow direct access to your mail server here.  If you need this done, please report it here and we will setup your mail server here for you.
