Verify if exim is actually listening on the external interface, for example on a remote server do "nmap xxx.xxx.xxx.xxx". If it doesn't report port 25 as open do the same on the local server, using your external IP. If that reports the port to be open you're filtering traffic. Change the filtering (check ipmasq for example, if you have it). If it also reports port 25 as closed you have to tell exim to listen to all interfaces.
