showq


SYNOPSIS

       showq [generic Postfix daemon options]


DESCRIPTION

       The showq daemon reports the Postfix mail queue status.  It is the pro-
       gram that emulates the sendmail ‘mailq’ command.

       The showq daemon can also be run in stand-alone mode by the  superuser.
       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 service 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; consequently, it cannot
       extract information from queue files in the maildrop directory.
