    What version of Postfix is shipped with Leopard?

            $ postconf mail_version mail_release_date

    Sounds like a "netinfo" problem. Is there some sort of "netinfo" listener
    that is recycled each hour? Perhaps the C-library getpwnam(3) fails for
    long-running processes as a result.

    Download the Postfix (say 2.4.6) source code, and build it, but don't
    install. Apply the following patch to src/global/mypwd.c, and in the
    src/global directory:

            $ make mypwd
            $ ./mypwd kes postfix nobody

    Let this run until it fails, or many hours later you get tired of waiting
    for a miracle. It will print lookup results for the three users once
    a minute. Report the results here.
