[SATLUG] Sendmail, postfix, alias expansion, and rewriting the "To:" header

So, I've got a sendmail-based mail server I'm working on, and I've got 
an aliases file with several entries similar to this:

groupone:  joe at domain.com, bill at domain2.com, suzy at domain3.com

I'd like to be able to send a message to groupone at mailserver.com, but 
have the message come across to each of the recipients as being 
addressed to each of them individually.

Is there an efficient way to use postfix (or something else?) to rewrite 
the "To:" header as the alias expands?
