Recently we've been having trouble sending emails to comcast.net accounts. We get message delayed notifications from our internal Exchange server. Some of the delay messages say our IP address is on the Vade Threat List and others say "Failed to connect. Winsock error code: 10051, Win32 error code: 10051." I have run our IP through many blacklist checkers and we are not on any that report. Can someone from Comcast help us? We have many clients with Comcast addresses and need to be able to send to them.
