FIOS seems to be blocking access to this IP. I use it as my SMTP server and it will not work from my FIOS machine, and I cannot even ping the address (it times out). If I go elsewhere, liek my Optimum system or http://network-tools.com, the address pings fine. Until today, I had no issues with it. When I googled the problem, I see Comcast had blocked the address at one time. Any idea what I can to to get my SMTP back?
