It's easy.  If you install using the port it will ask you what you'd like 
to do.  Typically you'd tell it to use mailer.conf to use postfix instead 
of sendmail and leave it at that.  man mailer.conf for more info, but the 
port will take care of it for you (or at least tell you what to do, it's 
been awhile since I set it up)
