If that's the right issue a simple search for hotmail.com file in your /mailroot/dnscache/mx/ dir should reveal the truth
mine contains the following: 3600 5:mx1.hotmail.com.,5:mx2.hotmail.com.,5:mx3.hotmail.com.,5:mx4.hotmail.com.

Some mailservers behind firewalls which do not allow transfer of UDP packets larger than 512 bytes may not be able to return the MX record If your firewall restricts UDP packet transfers though, you may want to verify that it will allow transfer of a MX record within the size limitations specified by RFC1035: http://www.faqs.org/rfcs/rfc1035.html Windows 2003 server has included Extension Mechanisms for DNS (EDNS0) to allow larger packets. If you run this command on a 2003 server: "dnscmd Server Name/Config /EnableEDnsProbes 0", it fixes it without making any changes to the firewall. - To unsubscribe from this list: send the line "unsubscribe xmail" in the body of a message to [EMAIL PROTECTED] For general help: send the line "help" in the body of a message to [EMAIL PROTECTED]
