From the inside, make sure that the smtp server is working:

telnet 25

if you get the standard banner, then 'quit' and attempt the same from the outside.  get the log info for that test and tell us what it says.

What do the logs say when you try to connect?  Is this smarthost behind the inside interface?  Are you testing by IP address or fully qualified domain name?
