I'm new to Exchange, so please forgive the broadness of this question. We have 2 mail servers in our company. One is running Exchange 2000, and one is running Rockliffe. The Rockliffe mail server works. The exchange server was brought in from a different office location. It used to work. Now, users can send out email, and recieve internal email, but nobody is recieving external email. Can somebody point me in the right direction? Thanks so much.

Where is the MX record for your domain pointing to, is it pointing to the exch 2k server?

Is the IMS connector set up correctly?

What bounce back messages are you receiving from the outside?

If you notify me thru the republic with the location of the mail server (postmaster@somedomain.com) I can test it and see what the bounce back message is.

First, the ISP you use must assign you a static IP address with a pointer to your domain name, I assume that since your Rockliffe mail server works you already have that in place]. Second is to configure your Exchange Server to "Always run" [always accept inbound x400, SMTP, communications via the Exchange X400 & SMTP ports]. Further, many ISP's [especially AOL] are requiring verified certificates before allowing Email servers to connect to theirs. It's possible that the certificate on the Exchange Server is invalid, expired, or nonexistant.

a simple test to check you Exchange server SMTP connector is via Telnet. Click start, run, type in cmd, click ok [or just type telnet.exe and click ok. At the telnet prompt, type in setlocal_echo. Press enter. Now type open25 press enter. You should see the Exchange Server version date and service pack date. If you do, at the telnet prompt, type helo. Exchange server should return a "Hello" with your external IP address. Next type ehlo. press enter. This will display the ehlo handshake that is used between email server. To exit the Exchange Connector type quit, press enter. At the Telnet prompt type q, press enter.

If you acommplished all that, then the E2K server is accepting incoming transmissions onport 25 and it's a matter of having the ISP static IP address [and domain name pointer]as the default for E2K. However, if your Rockliffe mail server is your Primary mail server and you wish the Exchange server to be a backup or back end mail server, this is a more elaborate setup and required configuration both in the Rockliffe mail server and E2K server. let us know

to clairfy the telnet commands[which after reading em it wasn't so clear] click start, run, and type in telnet.exe. press ok. This will open the telnet command prompt. At that prompt, type in setlocal_echo. press enter. Now just follow what I've laid out. note : means put a space between the words you type. means enter the actual domain name you use.
