[imp] can't email outside domain site

[Kent Martin]

What are your outbound mail settings, and, assuming you are using 
sendmail or a sendmail dropin replacement (exim/postfix/qmail/ssmtp) and 
assuming your mail settings relay mail through localhost, can you email 
from the command line?  You also want to make the apache user (or 
whatever user apache runs as) a "trusted user" in your MTA setup.

The file you are after is imp/config/servers.php, but, I cannot see how 
the problem could possibly be in there, it sounds like your MTA isn't 
set up right, or, your outbound address is no good and is getting 
rejected by the remote MTA.

The easiest way to see what is going on is to watch what is being 
written to the log file of your MTA when trying to send an email to an 
external domain.
