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 deleting 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 <b>main.cf</b> 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>-p</b> Produce a traditional sendmail-style queue listing. This option implements the traditional <b>mailq</b> com- mand, 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 delivered. If mail could not be delivered upon the last attempt, the reason for failure is shown. This mode of operation is imple- mented by executing the <a href="postqueue.1.html"><b>postqueue</b>(1)</a> command. 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 delivery 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>. The site must be eligi- ble for the "fast flush" service. 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</b> <b>-qR</b><i>site</i> command, by contacting the Postfix <a href="flush.8.html"><b>flush</b>(8)</a> daemon. <b>-v</b> Enable verbose logging for debugging purposes. Mul- tiple <b>-v</b> options make the software increasingly verbose. <b>SECURITY</b> This program is designed to run with set-group ID privi- leges, 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 <b>main.cf</b> 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 <b>main.cf</b> 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 <b>main.cf</b> parameters are especially relevant to this program. The text below provides only a parameter summary.
