    Interestingly enough after a "su - postfix", if I try
    to run nslookup as user postfix nslookup will hang
    with the following:

    $ nslookup
    *** Can't find server name for address 127.0.0.1: No
    response from server
    *** Default servers are not available

    So the unprivlidged user postfix can acess
    /usr/sbin/nslookup since the attempt to run this
    command didn't produce a "file not found" error.

    Any ideas?
