The only point to the telnet exercise is to determine if you can reach the server. You aren't logging in. You're not going to do anything while you're there. And, if it doesn't work, it doesn't really prove much. If you can get in to your mail servers at all, then there's nothing wrong with your system setup. With respect to Comcast, their server is bus occasionally or completely down (especially a couple of months ago). If you try it again, you'll usually get through. As for other mail servers, I'd suspect something similar. It could be that a particular server would be easier to connect to though other means that the default settings. Your email service provider could give you those advanced settings. Are you using Panther, btw? Mail 1.3 is infinitely better than previous versions.
