Hi - sorry for the long intro but please hang in there with me! After reading through loads of forums, FAQ's and setup guides I've become a bit confused.
I'm involved in setting up a new company and we've registered three domains (a .com, .co.uk and .net) and we've got a webserver at a webhost (Fasthosts) running Fedora 5 with Apache, Courier mail, Postfix mail transport agent and Bind 9 DNS).
We will be having SBS2003 and a static IP (which will be the firewall and will have the appropriate ports forwarded).
I've set up the A records for the domains to point to the webserver (somehow I've got the .co.uk and .net pointing to one IP, and the main domain .com pointing to the other - this I'll address!).
I intend setting up MX records to point to the static IP of the firewall with the priority of 10, and add an additional record to point to the webserver with the priority of 20 for backup if the SBS2003 is down for whatever reason.
For outgoing mail we'll probably relay through the office's ISP's mailserver to prevent sending problems (reverse DNS etc).
Can somebody advise if this is a good plan, or have I misunderstood how it works?
Is there anything else I should think about?
Is there anything security wise I should be worried about?
Many thanks in advance.
Justin
