I have had spotty on/off good/bad service from Comcast's built in relay server for years now. They finally broke what I had going on here, so I could not longer send my email out. After some searching, I found companies that will allow me to use them for relaying my email. The cost is quite affordable. I finally decided on DNSExit.com where I picked the 150 emails a day plan for a whole 1.99/mo. They actually had it less for a full year, but I wosn't sure if it was going to be worthe it or not. However, I CAN say that I no longer need to worry about my internet providers garbage anymore trying to restrict me running a business from a residential service.
