Recently the Comcast mail servers have proven to be quite the issue but I have found a workaround If you have express VPN and Pegasus Mail you occasionally get unable to connect authenticate and other VS messages back from our buddies at Comcast and I have traced the majority of the issue to the default settings in the VPN client to get a proper connection to their email servers you must set TCP in the client list otherwise you will not get a reliable connection to their servers since ice spent a bunch of time troubleshooting this I wanted to pass on my experience and what seemed to be the best fix Please excuse the grammar and spelling this is a speech to text program and wireless sometimes makes errors it still better than my typing
