Exchange Incoming mail

1. Make sure your CISCO is allows incoming connection to port 25 for SMTP to your server.
2. Make sure that your DNS MX (mail exchange) record points to your Exchange server IP (or the CISCO if you have tunelling). BTW, do you have a public IP onthe Exchange server network card?
3. Make sure you have the Internet Mail Connector installed and configured properly on your Exchange server and that your domain name is on the ROUTING tab as INCOMING. While you're at it, have a look at the QUEUES, as well.
4. Is internal e-mail working at all?
5. Enable Logging for mail transfer and have a look in the NT event log to see if any problems appear.
6. Send me an e-mail from one of the clients so I can see if you have a valid MX record andeverything is configured properly.
I hope some of this points will help.

internet mail connector is properly installed ....

i`m surprised as DNS(MX) records should be updated as we can send mails to internet to anyone just can`t receive from any client ...port is also open on router on internet address ...

The fastest and easiest way to troubleshoot this problem is to telnet to port 25 of your email servers from an outside ISP.
This will provide you the answers you're looking for.
Good luck!
