The easiest way of handling this is to use either a procmail recipe or use 
Maildrop (part of the Courier MTA but can also be used as a sendmail delivery 
agent).   The nice thing about maildrop is you can then create a default 
delivery 'filter' and then let users override that if they wish.  

I actually use SendMail + MailScanner + MailDrop + LDAP (virtual mail users) + 
Courier IMAP - creating the delivery DIR and shoving the user into LDAP and 
hey presto new mail user with no entry in /etc/passwd.
