What are the UNIX user names (LDAP "uid"s?) that correspond to the two
email addresses?

Show a sample LDAP entry in ldif format with the following attributes:

        dn:
        uid:
        mail: (or whatever field stores the official address of the user)

The email addresses can be used as keys for a virtual_alias_maps table
with the "uid" value mapping to a unique UNIX account name.

Unix account names MUST not contain "" characters. If you want the login
name to be the email address, and want to use LDAP auth, then don't use
PAM, dont make these into "local" users, and use virtual delivery.

Are these UNIX users, or are these IMAP/POP only users. Make up your mind.
This is not a Postfix issue per-se: what services are you providing to the
users, email-only accounts or system login accounts.
