    SHOWQ(8)                                                 SHOWQ(8)

    NAME
           showq - list the Postfix mail queue

    SYNOPSIS
           showq [generic Postfix daemon options]

    DESCRIPTION
           The  showq  daemon  reports the Postfix mail queue status.
           It is the program that emulates the sendmail `mailq'  com-
           mand.

           The  showq  daemon  can also be run in stand-alone mode by
           the super-user. This mode of operation is used to  emulate
           the `mailq' command while the Postfix mail system is down.

    SECURITY
           The showq daemon can run in a chroot  jail  at  fixed  low
           privilege, and takes no input from the client. Its service
           port is accessible to local untrusted users, so  the  ser-
           vice can be susceptible to denial of service attacks.

    STANDARDS
           None.  The showq daemon does not interact with the outside
           world.

    DIAGNOSTICS
           Problems and transactions are logged to syslogd(8).

    BUGS
           The showq daemon runs at a  fixed  low  privilege;  conse-
           quently, it cannot extract information from queue files in
           the maildrop directory.
