    Hi! Thank you for the tutorial.
    I've followed it on a Debian Etch and it always say:
    Jun 13 09:17:52 wiki postfix/pipe[7776]: 8CA122C8EC: to=<xxx@xxx>, relay=maildrop, delay=0.33, delays=0.09/0.03/0/0.21, dsn=5.1.1, status=bounced (user unknown. Command output: Invalid user specified. )

    Have you any idea of what could be wrong?
    Thank you!

    What's in /etc/postfix/main.cf and /etc/postfix/master.cf?

    I get the same output in my log. I've tried to set global read-, write- and execute perimission to the /var/run/courier/authdaemon/ directory and SUID to maildrop, neither helped.

    When I run "authtest user@mydomain.tld" I get
    Code:
    Authenticated: user@mydomain.tld  (uid 5000, gid 5000)
    Home Directory: /home/vmail
    Maildir: mydomain.tld/user/
    Quota: 0
    Encrypted Password: XXXXX
    Cleartext Password: (none)
    Options: (none)
    So it seems that the authentication works fine. But when I run "maildrop -d user@mydomain.tld" I get
    Code:
    Invalid user specified.
