Thanks I get ;; ANSWER SECTION: comcast.net. 300 IN MX 5 mx1h1.comcast.net. comcast.net. 300 IN MX 5 mx2h1.comcast.net. comcast.net. 300 IN MX 5 mx1a1.comcast.net. comcast.net. 300 IN MX 5 mx1c1.comcast.net. comcast.net. 300 IN MX 5 mx2c1.comcast.net. comcast.net. 300 IN MX 5 mx2a1.comcast.net. Are those new or old ones? I'm unable to send mail to comcast.net since a couple of days. The server fails saying "Did not find a suitable MX for a connection". When I tried manually mx1h1.comcast.net, the connection was closed before I could type "mail from". Best Ale --
