OK, please do not be offended at my responses as they may tend to be harsh. You need to learn about DNS and hosting e-mail services. DNS is extremely critical and is easily broken. In the forwarders list in your DNS server properties, you need to have your ISP DNS servers there, and nothing else. Forwards are for if your DNS server can not resolve a request, it forwards the request some one else. You have trouble receiving from the Internet because the public DNS record only has one MX record, and that is pointed at your ISP server saf.tzo.com. Unless you configure Exchange to retrieve your mail from there if that server is set up to receive your mail, you will never get it. I was able to send 2 test messages through that server, so it is accepting mail.

What is you external DNS server and what is the MX record on it? The only public MX record showing up is saf.tzo.com. All external e-mail will go to that server only. Also, there is only one host record (A) which resolves jedgroup.com. In our forward zone, we named jedgroup.com to the internal address (one adapter) and www.jedgroup.com to the external address, the 2nd adapter. > Are you having problems receiving e-mail sent from internal, Internet or both? We have trouble only receiving from the Internet. The Internal works fine. > You mentioned 3 different pieces of hardware, what are they for? (Gateway, Internet cable and Linksys router.) Can you please explain your network setup. >From the Cable Modem: to the Linksys router to the first (www.jedgroup.com) adapter on the SBS2000 Server then the internal network adapter to the switch then to the workstations.
