I'm in the middle of migrating and configuring a web server with two domains (with one more in the future), and no sub-domains so far, but using a single IP address (for now). This type of configuration should be able to accommodate many corporate email accounts created under one domain, and just a few associated under the other one (an e-store). I have doubts about how to set up this on an old Debian Squeeze 6 (Apache 2.2.16, BIND 9.7.3, Exim 4.72, Dovecot 1.2.15).
I've took some pointers from these sites:
But I still can't find a good resource for the BIND configuration with many domains using only one IP. So, I want to be sure everything is in place before shutdown one server and start using the newly configured one, so any advice about multiple domains and multiple emails with one IP address, on the same server, would be appreciated.
