You could also use LDAP as the backend instead of the UNIX passwd 
database. You can create shell users out of them if you want to using 
libnss-ldap and libpam-ldap.

I use this kind of setup with dovecot and qmail-ldap. You can give a 
custom filter to dovecot to search for as well, so I can disable users 
in the MTA and IMAP/POP3 just by setting:

accountStatus: disabled

in the DN for that user.
