.TH POSTDROP 1
.ad
.fi
.SH NAME
postdrop
\-
Postfix mail posting utility
.SH "SYNOPSIS"
.na
.nf
\fBpostdrop\fR [\fB\-rv\fR] [\fB\-c \fIconfig_dir\fR]
.SH DESCRIPTION
.ad
.fi
The \fBpostdrop\fR(1) command creates a file in the \fBmaildrop\fR
directory and copies its standard input to the file.
Options:
.IP "\fB\-c \fIconfig_dir\fR"
The \fBmain.cf\fR configuration file is in the named directory
instead of the default configuration directory. See also the
MAIL_CONFIG environment setting below.
.IP \fB\-r\fR
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.
.IP \fB\-v\fR
Enable verbose logging for debugging purposes. Multiple \fB\-v\fR
options make the software increasingly verbose. As of Postfix 2.3,
this option is available for the super\-user only.
.SH "SECURITY"
.na
.nf
.ad
.fi
The command is designed to run with set\-group ID privileges, so
that it can write to the \fBmaildrop\fR queue directory and so that
it can connect to Postfix daemon processes.
.SH DIAGNOSTICS
.ad
.fi
Fatal errors: malformed input, I/O error, out of memory. Problems
are logged to \fBsyslogd\fR(8) or \fBpostlogd\fR(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.
.SH "ENVIRONMENT"
.na
.nf
.ad
.fi
.IP MAIL_CONFIG
Directory with the \fBmain.cf\fR file. In order to avoid exploitation
of set\-group ID privileges, a non\-standard directory is allowed only
if:
.RS
.IP \(bu
The name is listed in the standard \fBmain.cf\fR file with the
\fBalternate_config_directories\fR configuration parameter.
.IP \(bu
The command is invoked by the super\-user.
.RE
.SH "CONFIGURATION PARAMETERS"
.na
.nf
.ad
.fi
The following \fBmain.cf\fR parameters are especially relevant to
this program.
The text below provides only a parameter summary. See
\fBpostconf\fR(5) for more details including examples.
.IP "\fBalternate_config_directories (empty)\fR"
A list of non\-default Postfix configuration directories that may
be specified with "\-c config_directory" on the command line (in the
case of \fBsendmail\fR(1), with the "\-C" option), or via the MAIL_CONFIG
environment parameter.
.IP "\fBconfig_directory (see 'postconf -d' output)\fR"
The default location of the Postfix main.cf and master.cf
configuration files.
.IP "\fBimport_environment (see 'postconf -d' output)\fR"
The list of environment parameters that a privileged Postfix
process will import from a non\-Postfix parent process, or name=value
environment overrides.
.IP "\fBqueue_directory (see 'postconf -d' output)\fR"
The location of the Postfix top\-level queue directory.
.IP "\fBsyslog_facility (mail)\fR"
The syslog facility of Postfix logging.
.IP "\fBsyslog_name (see 'postconf -d' output)\fR"
A prefix that is prepended to the process name in syslog
records, so that, for example, "smtpd" becomes "prefix/smtpd".
.IP "\fBtrigger_timeout (10s)\fR"
The time limit for sending a trigger to a Postfix daemon (for
example, the \fBpickup\fR(8) or \fBqmgr\fR(8) daemon).
.PP
Available in Postfix version 2.2 and later:
.IP "\fBauthorized_submit_users (static:anyone)\fR"
List of users who are authorized to submit mail with the \fBsendmail\fR(1)
command (and with the privileged \fBpostdrop\fR(1) helper command).
.PP
Available in Postfix version 3.6 and later:
.IP "\fBlocal_login_sender_maps (static:*)\fR"
A list of lookup tables that are searched by the UNIX login name,
and that return a list of allowed envelope sender patterns separated
by space or comma.
.IP "\fBempty_address_local_login_sender_maps_lookup_key (<>)\fR"
The lookup key to be used in local_login_sender_maps tables, instead
of the null sender address.
.IP "\fBrecipient_delimiter (empty)\fR"
The set of characters that can separate an email address
localpart, user name, or a .forward file name from its extension.
