All, I have Googled and searched the archives for two days and cannot find an answer to this question... just more confusion! Please forgive me ahead of time as I run two name servers for my mid-sized company and am by no means an expert in using bind DNS. We have about eight domains but don't have a lot of records for each zone. Here is my issue:
We are moving to a two Exchange server / two data center model for auto-failover reasons. Both data centers are in to different locations and have multiple internet pipes and tier 1 providers coming into their data centers. Here is what I'm trying to do: For example, our email domain name on the Exchange servers is: mail.blahblah.us Our spam filtering device is: spam.blahblah.us and is the MX record. In the blahblah.us zone file I have A records pointing to both correctly. Our problem comes in on our other domains. I am trying to point mail.company1.com to mail.blahblah.us and spam.company1.com to spam.blahblah.us using CNAME records. I'm obviously doing this wrong or trying to do something that can't or shouldn't be done. Like I said, I am fairly new to bind9 but I'd sure rather use it than something link MS DNS servers! What I am attempting to do is make it so that if an outside email server or inside user goes to mail.company1.com or spam.company1.com they are 'redirected' to the blahblah.us domain where our UCC cert covers both of the Exchange servers. Please let me know if I've left anything out that would be helpful in answering these questions. Thank you, Scott
