Options: <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>-r</b> Use a Postfix-internal protocol for reading the message from standard input, and for reporting status information on standard output. This is currently the only supported method. <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> The command is designed to run with set-group ID privileges, so that it can write to the <b>maildrop</b> queue directory and so that it can connect to Postfix daemon processes. <b>DIAGNOSTICS</b> Fatal errors: malformed input, I/O error, out of memory. Problems are logged to <b>syslogd</b>(8) and to the standard error stream. When the input is incomplete, or when the process receives a HUP, INT, QUIT or TERM signal, the queue file is deleted. <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.
