You'll need to specify a virtual_maps file. Take a look at the sample_virtual.cf file (probably in /etc/postfix/), which should get you pointed in the right direction. The virtual file will need to contain something like the following: domainname.com virtual address at domainname.com username address2 at domainname.com username otherdomain.com virtual address at otherdomain.com username Whitespace is significant in this file. Don't forget to run 'postalias' on this file after you make changes (it needs to be hashed, much like /etc/aliases). Username above represents the user on the system that should get e-mail sent to that address. If you've got lots of domains that you're hosting it can be a pain to maintain, but it does allow you to do neat things like having info at domainname.com and info at otherdomain.com go to their respective domain owners (which I could never figure out how to do under sendmail, but I'm sure sendmail could do it also). You do not need to specify a virtual entry for whatever domain your box is set to respond as in /etc/postfix/main.cf. Also, if you feel like spending some money, I'd recommend a book: 'Postfix' by Richard Blum, published by SAMS. The ISBN is 0-672-32114-9.
