I'm about to embark on upgrading our current network structure (Windows 2000 Server - DC, Windows 98 - running VPOP3 Mail Server & Comodo Trustix 4) with a new server running SBS 2003. One of the areas that I'm obviously looking to implement is Exchange. I'd like to receive the mail directly to my server (rather than POP3 thru my ISP) but I'm a bit confused as to who I should speak to about setting this up.
I believe that I need to contact my ISP (that is hosting my domain) to setup a MX record for my DNS domain (ie my MX record is domain.com so server would be addressed as servername.domain.com). I also need an A Level entry (A=servername.domain.com and this is to point to the external IP address of my firewall) - this was read from question 21112412. I then need to configure the Exchange Server on SBS 2003 accordingly. Is this correct?
Now the main problem I have is that our organisation is supplied their internet access from British Telecom using an Intelligent Gateway Router (a 1Mb line). We have a static IP address supplied by them for our connection. Our website (domain) is hosted by a company called Clearfuse and our current POP3 provider is called Onthespot. Now who should I contact to setup this MX record to point to our server? I would have thought it would be Clearfuse as they host the domain but they are not our ISP.
Also, would I use my server as the primary DNS Server after all of this or should it point to my ISP? At present we have no thoughts of bringing the external website hosted by Clearfuse into the internal server. We'll prehaps open Sharepoint for Internet use at some stage but no right away.
Any advice is welcome as always.
