PIX/Exchange server config

I have an application server hosted outside my firewall.
I use PIX 506E as our firewall

I have an exchnage server 2000 in our LAN for our internal usage. This is not published and cannot be accessed from outside.

I want an application from the app. server to send a mail to this exchange server. I mapped a static ip to this exch server and added the app. server Ip in the relay server properties of the SMTP.

I opened the SMTP port in firewall also.

Now I able to ping from App. server to exch server and vice versa. From the application server, I am able to open the Web access and see the mails.

I added the Exchange server's IP as one of the DNS servers in the Application server.

Still I am not able to send mail from application server to exchange server. When I try to send mail, it keeps waiting at queue folder.

Please advice.

magesh if ur app server is ina separate forest (or work group)then it has no clue where to send the email.emails are routed based on MX records
by utilizing smtp servers,connectors and smart hosts.U may try creating an MX record in ur external dns server for ur internal exchange server(u already have the static mapping done)and see if that would help.
thanks magesh but how did u fix ur problem?
