I just use the mailertable feature of sendmail.

Edit the contents of /etc/mail/mailertable

To do all mail put a single line in it.

.       smtp:[]

Then run make && make restart from the /etc/mail directory, Sendmail 
will then forward all mail to the mail server specified. You can also 
add secondary server using a : as a separator.
