OK, Here is the skinny on the problem. We bought another ISP who happens to be running Imail V5.04 and using a Linux DNS server. We did not buy out the whole company so their mail server remains their own. They have two NS machines NS.CASTLEGATE.NET and NS.FIRSTPLACE.NET, The main domain is castlegate.net. I put a new IP address on my mail server and told Imail V5.07 that it is mail.castlegate.net and the alternate name is castlegate.net. One of our owners had the other company put our Primary DNS server as their secondary. Remember that castlegate.net is the other company's primary domain name! We got castlegate.net customers to work just fine BUT all the domains that she is hosting were having a problem. People could get to their web pages just fine but when they tried to get to their email from our system they would constantly get the web site rather than their mail server which is now known as imail.castlegate.net. The strange thing is our mail server cannot seem to get the correct MX record from their machine. Yet if we check their machine it gives the proper answer of 207.168.201.15 for the MX record and our DNS responds properly as well. As a result we had the other company change their DNS records so that each domain on their system shows the mail server. So when you type the name kellyford.com the result is 207.168.201.15 if you type www. in front it goes to the web page. If I did not mention it before these are all virtual domains on their mail server. Any clues?
