I use the port mail/ssmtp for this purpose. This is a small program that 
sends all mails via a relay server. After you have installed it you will 
find some example configuration files in /usr/local/etc/ssmtp. Alter 
also the entries in /etc/mail/mailer.conf to

sendmail        /usr/local/sbin/ssmtp
send-mail       /usr/local/sbin/ssmtp
mailq           /usr/local/sbin/ssmtp
newaliases      /usr/local/sbin/ssmtp
hoststat        /usr/bin/true
purgestat       /usr/bin/true
