Folks, You may or may not have noticed we've been moving some things around. We've published new MX records, and have moved traffic over. The old MX records will cease to exist shortly. If you're somehow fixated on those old MX records or associated IPs, your traffic to comcast.net recipients may not work much longer. Please let us know if you have any questions or concerns. 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".
