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>SECURITY</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>DIAGNOSTICS</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>ENVIRONMENT</b> 47 MAIL_CONFIG 48 Directory with the <a href="postconf.5.html"><b>main.cf</b></a> file. In order to avoid exploitation 49 of set-group ID privileges, a non-standard directory is allowed 50 only if: 51 52 <b>o</b> The name is listed in the standard <a href="postconf.5.html"><b>main.cf</b></a> file with the 53 <b><a href="postconf.5.html#alternate_config_directories">alternate_config_directories</a></b> configuration parameter. 54 55 <b>o</b> The command is invoked by the super-user. 56 57<b>CONFIGURATION PARAMETERS</b> 58 The following <a href="postconf.5.html"><b>main.cf</b></a> parameters are especially relevant to this pro- 59 gram.
