Hello
To use the native ability of SBS Exchange to host your own mail, there are a few things you should check.
First, be sure your SBS server and all the server apps are fully patched, including Exchange and ISA. Run the MS Baseline Advisor to be sure.
http://www.microsoft.com/technet/security/tools/mbsahome.mspx
Install or update real-time antivirus for Exchange - many like Trend's Client Server Messaging for SMB
Install or update an anti spam solution, again Trend, or GFI are often recommended. You may consider a hardware appliance to take care of this.
You will need either a static IP address for your router/firewall or a service that collects requests for your FQDN and forwards it to your often changing dynamic ip address.
http://www.dyndns.com - among others will do this for you.
Contact your ISP and verify that they will support you in this. Verify that they do not block traffic on port 25. You will need them to create a MX and a PRT (reverse DNS) record. Some ISP's allow/make you do this yourself on their management pages for your account. Others set this up for you.
You might want a SPF record designating your mx record as an authorized sender of mail from your domain. Have a look at www.openspf.org <http://www.openspf.org>
To avoid missing any mail when you are off line, you can ask your ISP to, (or change to an ISP who will), create a backup mail server with a lower priority cache than the record for your mail server. If you are off line, they will hold your mail until you come back. Ask the folks in New Orleans about being off line for days, or weeks.
You will need to configure your router/firewall to accept inbound connections on port 25 and forward them to the ip address of your SBS exchange server on the subnet that you have connected to the router/firewall. In the case of two nic installations, this should be the second, or "external" nic.
Once all the preparations are done, the last step is to run the CEICW to set all the settings and tell Exchange what what the reply domain address is. If you have multiple domains you can set up additional SMTP addresses, but there can be only one default reply address.

we currently have our internal network as company.local, and also have
company.org which is a website hosted by an external provider
what i would like to do is route all email through exchange on our server
here, bypassing the isp
i understand that i cant rename the domain in sbs2k3 but would that be
necessary? or do i just have a few things to do in system manager/the ISP?
