SHOWQ(8) SHOWQ(8)
<b>NAME</b>
showq - list the Postfix mail queue
<b>SYNOPSIS</b>
<b>showq</b> [generic Postfix daemon options]
<b>DESCRIPTION</b>
The <b>showq</b> daemon reports the Postfix mail queue status.
It is the program that emulates the sendmail `mailq' com-
mand.
The <b>showq</b> 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.
<b>SECURITY</b>
The <b>showq</b> 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.
<b>STANDARDS</b>
None. The showq daemon does not interact with the outside
world.
<b>DIAGNOSTICS</b>
Problems and transactions are logged to <b>syslogd</b>(8).
<b>BUGS</b>
The <b>showq</b> daemon runs at a fixed low privilege; conse-
quently, it cannot extract information from queue files in
the <b>maildrop</b> directory.
