    Some side bits of information.

    Megyer Laszlo <lezsch.bme.hu> probably said:

    Why, thank you for letting Philip Hazel (who is on holiday right now)
    get a patched version out before announcing this to bugtraq.

    This is not the default location for exim.

    and no one with sense runs an MTA as root, and the exim security
    information strongly suggests you do not. On my relays the MTA runs as
    root only once at boot time to bind to port 25 and is not suid root.

    Yes, this looks like a real problem but it should also serve as a good
    time to check that as little as possible runs as root.

    P.
