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:

and poking around the archives.

Also, the documentation is very well put together:

You may also want to consider grabbing a copy of  "The book of postfix":

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.
