Switched to Cisco 2621 and problems arise

I switched to a cisco 2621 from a bay asn. I can no longer receive emails from the outside world. I can get it internally, I can surf the net, but no emails are coming in from the outside. What do you suggest I check? I used config maker for this router and it has put a no access list section in the ios config. I don't have any access lists running. The only thing out of normal I use is NAT. Thanks.

Running config from the router with the ip address of the email server etc will be good information to start in this regards...

Now are you able to telnet on tcp port 25 to the ip address of the email server from the router using outside public ip address?

For exa..outside interface is serial0 with ip 1.1.1.1 (public) and email server ip is 2.2.2.2 (privet)

Then command to try on the router will be

telnet 2.2.2.2 25 /source-interface serial0

Thx..Tejal
