See also the MAIL_CONFIG 25 environment setting below. 26 27 <b>-r</b> Use a Postfix-internal protocol for reading the message from 28 standard input, and for reporting status information on standard 29 output. This is currently the only supported method. 30 31 <b>-v</b> Enable verbose logging for debugging purposes. Multiple <b>-v</b> 32 options make the software increasingly verbose. As of Postfix 33 2.3, this option is available for the super-user only. 34 35 <b><a name="security">SECURITY</a></b> 36 The command is designed to run with set-group ID privileges, so that it 37 can write to the <b>maildrop</b> queue directory and so that it can connect to 38 Postfix daemon processes. 39 40 <b><a name="diagnostics">DIAGNOSTICS</a></b> 41 Fatal errors: malformed input, I/O error, out of memory. Problems are 42 logged to <b>syslogd</b>(8) or <a href="postlogd.8.html"><b>postlogd</b>(8)</a> and to the standard error stream. 43 When the input is incomplete, or when the process receives a HUP, INT, 44 QUIT or TERM signal, the queue file is deleted. 45 46 <b><a name="environment">ENVIRONMENT</a></b> 47 MAIL_CONFIG 48 Directory with the <a href="postconf.5.html"><b>main.cf</b></a> file.
