See also the MAIL_CONFIG 24 environment setting below. 25 26 <b>-r</b> Use a Postfix-internal protocol for reading the message from 27 standard input, and for reporting status information on standard 28 output. This is currently the only supported method. 29 30 <b>-v</b> Enable verbose logging for debugging purposes. Multiple <b>-v</b> 31 options make the software increasingly verbose. As of Postfix 32 2.3, this option is available for the super-user only. 33 34<b>SECURITY</b> 35 The command is designed to run with set-group ID privileges, so that it 36 can write to the <b>maildrop</b> queue directory and so that it can connect to 37 Postfix daemon processes. 38 39<b>DIAGNOSTICS</b> 40 Fatal errors: malformed input, I/O error, out of memory. Problems are 41 logged to <b>syslogd</b>(8) or <a href="postlogd.8.html"><b>postlogd</b>(8)</a> and to the standard error stream. 42 When the input is incomplete, or when the process receives a HUP, INT, 43 QUIT or TERM signal, the queue file is deleted. 44 45<b>ENVIRONMENT</b> 46 MAIL_CONFIG 47 Directory with the <a href="postconf.5.html"><b>main.cf</b></a> file. In order to avoid exploitation 48 of set-group ID privileges, a non-standard directory is allowed 49 only if: 50 51 <b>o</b> The name is listed in the standard <a href="postconf.5.html"><b>main.cf</b></a> file with the 52 <b><a href="postconf.5.html#alternate_config_directories">alternate_config_directories</a></b> configuration parameter. 53 54 <b>o</b> The command is invoked by the super-user. 55 56<b>CONFIGURATION PARAMETERS</b> 57 The following <a href="postconf.5.html"><b>main.cf</b></a> parameters are especially relevant to this pro- 58 gram.
