Last week I bit the bullet and ordered a static ip for my SBS server. It only costs $5/month extra. Yesterday I was informed it was ready to go in the traditional tech support way, my network stopped communicating with the internet. When I called to report the problem, they said I needed to update my router with the static IP address. Next I asked my web server provider to install an A record for the subdomain. That was finally ready today. I checked it using NSLOOKUP and www.dnsstuff.com. Then I ran ICEW and created a certificate for the new fully qualified domain name(FQDN). My final test was to login to OWA.
Since everything was working for http access I went back and ran ICEW again. This time I told it to change my email to use DNS rather than Smarthost to send mail. To test the outbound access I sent an email to my yahoo email address. Before I changed my MX record I decided to check my configuration for open SMTP relay. That is where I ran into this article. My server passed the test so I am ready to go live.
