For some reason my email ports and most all of the others are closed and I can figure out why. I contacted the company hosting my domain and they aren't blocking anything, I contacted my ISP and they are blocking anything. I changed ISP from Verizon to Comcast and the first hour with the new Comcast router I was able to get email and I thought I had the problem solved but after about an hour Port 110 and 25 are closed again and I couldn't get email. I purchased my own cable modem and an ASUS router. again for the first hour I was able to get email and then again about an hour later the ports are closed again. I've been trying to figure out why the port are closed. This is effecting all of my computers. I can RDP to to my server and I can get on the Internet, I just can get email and I have Mouseshare which allows me to control three computers from one keyboard and mouse, It stopped working as will because the port it is using is closed also. Has anyone had this problem?
