I run OpenBSD on my mailservers, but I expect that the sendmail works 
basically the same.

In /etc/rc.conf or its FreeBSD equivalent, check the sendmail line to 
see if it references localhost.cf or sendmail.cf

localhost.cf will permit internal mail on the machine, so that root can 
send messages to your everyday UID, etc., but will not permit mail to be 
sent to or received from, the Internet, or other machines in you LAN.

sendmail.cf will permit full Internet email, but even this will not 
permit Internet email, unless your machine has a fully Qualified Domain 
Name, which is registered with your domain registrar, and has the 
Registrar's MX setting configured properly.
