Our Web Server recently crashed and i have Rebuilt it.  It needs to be able to send email (We run Exchange 2003).I have set up the Virtual SMTP Server to point to a Smart Host on the Front End Server.  Yet, I still cannot send email!  I have ensured that the relay permissions are set up on this server as well as the FES.

What am I missing!!!

what is the application pointing to that sends the mail? have you tried pointing the application to the exchange server as its smtp server?

what settings do you have in the relay permissions on the exchange server?

have you tried sending a mail through telnet from the webserver  via the exchange server? what was the results?

any NDR's?

Thank you for responding.  Hopefully I understand your questions:

the application that sends the mail is pointing to the default SMTP Server our Front End Server.

On the Exchange Server Itself, i have set the IP Address Range of the server to the Relay tab in the SMTP Properties of the Exchange Server and the Web Server.

That is another thing that i discovered after posting is that I cannot Telnet into the Exchange Server from the Web server, but can from Exchange to the Web Server.  Is is possible that the cdosys does not have the proper permissions and I need to register it on the Web server???

Unfortunately No NDR's.

Thanks For your help!!!

ok is this exchange front end on the LAN? or is it in a DMZ? if you cannot telnet to the exchange server something is blocking it. does this new webserver have the same IP as the old one that crashed?

THe Front End Server has 2 NIC, one on the inside LAN and one in the DMZ.  I finally was able to telnet in (McAfee Port Blocking), but mail still does not flow.

Yes, it has the same IP and the same name

We figured it out.  Instead of using the Smart Host, we took that out of the mix and all is well with the world again.  THANKS for the INSTIGHT
