POSTDROP(1) POSTDROP(1)
<b>NAME</b>
postdrop - Postfix mail posting utility
<b>SYNOPSIS</b>
<b>postdrop</b> [<b>-rv</b>] [<b>-c</b> <i>config</i><b>_</b><i>dir</i>]
<b>DESCRIPTION</b>
The <a href="postdrop.1.html"><b>postdrop</b>(1)</a> command creates a file in the <b>maildrop</b>
directory and copies its standard input to the file.
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 sta-
tus information on standard output. This is cur-
rently the only supported method.
<b>-v</b> Enable verbose logging for debugging purposes. Mul-
tiple <b>-v</b> options make the software increasingly
verbose. As of Postfix 2.3, this option is avail-
able for the super-user only.
<b>SECURITY</b>
The command is designed to run with set-group ID privi-
leges, so that it can write to the <b>maildrop</b> queue direc-
tory and so that it can connect to Postfix daemon pro-
cesses.
<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.
