Won't the virtual users still need to access their mailbox? I think that is what
Josip was getting at. How do your virtual users read their mail?

If it's by Webmail, POP, IMAP then presumably they need to authenticate to
access it. That authentication can be handled by pam_ldap, using the relevant
attributes in the LDAP directory. You can also use LDAP to specify the user's
home directory, and this can be created automatically when they receive their
first message by the appendfile transport.
