Bounced mails accumulate in Postfix queue

    I'm trying to configure our server so that it can be used as a smarthost for one domain. All outgoing mails will be sent through this server and all incoming mails are handled by some other service.

    I've created one single mailbox (say [email protected]). All users use the credentials of this mailbox to authenticate with the Postfix server and then send the mails using their real "from" addresses (e.g. [email protected], [email protected]). This works basically fine. However, when one of these mails bounces back, it seems that Postfix tries to handle the bounce message locally. This fails because there is no local inbox for e.g. [email protected] (as said, incoming mails are handled elsewhere). As a consequence, the bouncing mails accumulate in the postfix queue with a message like this:

    (temporary failure. Command output: /usr/bin/maildrop: Unable to create a dot-lock at /var/vmail/
    Is there any way to deliver the bounced message to the server actually handling the incoming mail (as designated by the MX record)?


    OS: Debian 6.0.9
    ISPConfig version:
    Postfix version: 2.7.1-1+squeeze1
