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 superuser. 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. <b>SEE</b> <b>ALSO</b> <a href="cleanup.8.html">cleanup(8)</a> canonicalize and enqueue mail <a href="pickup.8.html">pickup(8)</a> local mail pickup service <a href="qmgr.8.html">qmgr(8)</a> mail being delivered, delayed mail syslogd(8) system logging <b>LICENSE</b> The Secure Mailer license must be distributed with this software. <b>AUTHOR(S)</b> Wietse Venema IBM T.J.
