Postfix can use the existing /etc/aliases file.
As this is getting to be more off-topic from FreeBSD, I would suggest
subscribing to the Postfix mailing list:
http://www.postfix.org/lists.html
and poking around the archives.
Also, the documentation is very well put together:
http://www.postfix.org/documentation.html
You may also want to consider grabbing a copy of "The book of postfix":
http://nostarch.com/frameset.php?startat=postfix_rev
It can be obtained either in paper or electronic format. I have the pdf
sitting on my 'desktop' for a readily available reference. It has helped
me out in answering a vast number of questions I had without the aide of
the mailing list.
