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.
