MX and A records delima for Exchange and web site Hosting

Posted on 2007-10-18
Last Modified: 2013-11-30
We recently took over an office that has an exchange server, they had a hoster that was doing the web page and controlling the records(ie dns, mx, a and so on). The hoster went out of business and now we have transfered to a new hoster but the only way to get the exchange e-mail server working is to point the MX records to the and the A record to the IP of the exchange server. Now my exchange server mail that i controll works but the web site that they (the people we transfered to)are hosting will not work. if they change the A record to the web site comes up but the my mail server quits sending mail. I guess what i am asking is am i missing something on the exchange server settings for the new hoster or are they pointing something wrong.

    They are most likely using a generic @ record point to the ip address of the website. Then www is just pointed to @. The same with mail. The key here is to break the records out and not use cname.

    Create an A record for www


    Create an A record for mail


    Now create an MX record and point it to the A record you just created for mail.

    Hope this helps

    The exchange server usually use the DNS configured manually at the SMTP connector level. There you will find something like use external DNS to routing email. You can check this to see if that address is pointing to a working DNS server. For external DNS you can test using, but first configure DNS like redcelltech sayed.

    Good luck
