It implements operations that are traditionally available via the <a href="sendmail.1.html"><b>sendmail</b>(1)</a> command. See the <a href="postsuper.1.html"><b>postsuper</b>(1)</a> command for queue operations that require super-user privileges such as delet- ing a message from the queue or changing the status of a message. The following options are recognized: <b>-c</b> <i>config</i><b>_</b><i>dir</i> The <a href="postconf.5.html"><b>main.cf</b></a> configuration file is in the named directory instead of the default configuration directory. See also the MAIL_CONFIG environment setting below. <b>-f</b> Flush the queue: attempt to deliver all queued mail. This option implements the traditional "<b>sendmail -q</b>" command, by contacting the Postfix <a href="qmgr.8.html"><b>qmgr</b>(8)</a> daemon. Warning: flushing undeliverable mail frequently will result in poor delivery performance of all other mail. <b>-i</b> <i>queue</i><b>_</b><i>id</i> Schedule immediate delivery of deferred mail with the specified queue ID. This option implements the traditional <b>sendmail -qI</b> command, by contacting the <a href="flush.8.html"><b>flush</b>(8)</a> server. This feature is available with Postfix version 2.4 and later. <b>-p</b> Produce a traditional sendmail-style queue listing. This option implements the traditional <b>mailq</b> command, by contacting the Postfix <a href="showq.8.html"><b>showq</b>(8)</a> daemon. Each queue entry shows the queue file ID, message size, arrival time, sender, and the recipients that still need to be deliv- ered. If mail could not be delivered upon the last attempt, the reason for failure is shown. The queue ID string is followed by an optional status character: <b>*</b> The message is in the <b>active</b> queue, i.e. the message is selected for delivery. <b>!</b> The message is in the <b>hold</b> queue, i.e. no further deliv- ery attempt will be made until the mail is taken off hold. <b>-s</b> <i>site</i> Schedule immediate delivery of all mail that is queued for the named <i>site</i>. A numerical site must be specified as a valid <a href="http://tools.ietf.org/html/rfc5321">RFC</a> <a href="http://tools.ietf.org/html/rfc5321">5321</a> address literal enclosed in [], just like in email addresses. The site must be eligible for the "fast flush" ser- vice. See <a href="flush.8.html"><b>flush</b>(8)</a> for more information about the "fast flush" service. This option implements the traditional "<b>sendmail -qR</b><i>site</i>" com- mand, by contacting the Postfix <a href="flush.8.html"><b>flush</b>(8)</a> daemon. <b>-v</b> Enable verbose logging for debugging purposes. Multiple <b>-v</b> options make the software increasingly verbose. As of Postfix 2.3, this option is available for the super-user only. <b>SECURITY</b> This program is designed to run with set-group ID privileges, so that it can connect to Postfix daemon processes. <b>DIAGNOSTICS</b> Problems are logged to <b>syslogd</b>(8) and to the standard error stream. <b>ENVIRONMENT</b> MAIL_CONFIG Directory with the <a href="postconf.5.html"><b>main.cf</b></a> file. In order to avoid exploitation of set-group ID privileges, a non-standard directory is allowed only if: <b>o</b> The name is listed in the standard <a href="postconf.5.html"><b>main.cf</b></a> file with the <b><a href="postconf.5.html#alternate_config_directories">alternate_config_directories</a></b> configuration parameter. <b>o</b> The command is invoked by the super-user. <b>CONFIGURATION PARAMETERS</b> The following <a href="postconf.5.html"><b>main.cf</b></a> parameters are especially relevant to this pro- gram. The text below provides only a parameter summary.
