SHOWQ(8) System Manager's Manual 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' command. 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 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. SEE ALSO
