It depends a little on what packages he installed for the mailserver.
However most (maybe all, i'm not sure) of the mailservers keep their
logs in the same place.

A good start would be: check the server has outgoing smtp connectivity
(telnet to a known good smtp server on port 25 and go though the
helo/mail from/rcpt to  procedure.) If you can mail from the command
line its an issue with the mailserver, if not its a firewall/network issue.
	Next check the maillogs (/var/log/maillog) and the messages log
(/var/log/messages) to see if anything obvious is in them.
	If you are using the base sendmail (or another MTA via the mailwrapper)
it can be restarted using "/etc/rc.d/sendmail restart"

I'd suggest looking through the handbook as well
(http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/)
especially the
http://wwwfe.freebsd.org/doc/en_US.ISO8859-1/books/handbook/mail.html
section.

If you have error messages in the logfile you cant understand and
restarting sendmail doesnt fix it, send it to the list (I wont be
checking my email much for the rest of today so keep it on list so
others can help)
