NAME
showq - list the Postfix mail queueSYNOPSIS
showq [generic Postfix daemon options]
DESCRIPTION
The daemon reports the Postfix mail queue status. The output is meant to be formatted by the postqueue(1) command, as it emulates the Sendmail `mailq' command.
SECURITY
The 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 daemon does not interact with the outside world.
DIAGNOSTICS
Problems and transactions are logged to syslogd(8) or postlogd(8).
