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.
