Few things you can try:
1. Using telnet on your exchange server, try and connect to an external mail server on port 25.
2. Do the reverse - outside your LAN, check you can telnet into your mail server on port 25.
3. Check whether you need to have your ISP setup as your SMTP host/gateway (here we have our own exchange server, but send mail to nildram (Our ISP) in exchange
4. Using nslookup, check that the MX records point to your exchange server external IP
eg, by typing
It should give you the IP address of your exchange box/firewall
The checks above will show if there is actually a route insideand out for smtp email, if they fail you should check your firewall/IP setup.

Depending who your ADSL ISP is they may also be throttling SMTP traffic in which case you will have to use their SMTP server as a forwarder (similar for receiving too)
