[Dovecot] P0P3 problems

[Nick]

    Hi,
           I'm setting up Dovecot on a Linux (Ubuntu) server and IMap
    works but P0P3 doesn't.  When I try to get the eMail, it appears
    to do everything it should (no errors) but nothing gets downloaded.

    I'm also a little confused with this:
    If I select either "Password authentication source" Unix passwd or
    shadow file (using WEBmin or text edit the config file) Dovecot
    errors:  Unknown setting: line 648: and yet, if I take it out it
    works fine.  How does Dovecot get the passwords if no source is
    included ???

                            Please advise,
                                              Thanks,
                                                       Nick. . .
