You really should be using a virtual domain configuration, unless you 
have some other reason to give every user a unix account (like they are 
also going to need shell access).  I don't know Postfix that well, but I 
do know that there are multiple ways to do it (including MySQL support). 
  A virtual domain is going to be far easier to manage than creating 4k 
different accounts.

As for how to stitch username at domain.com => username-domain.com you 
should be able to use

	default_mail_env = maildir:~%u-%d/Maildir

or whatever that points to their home directory.
