.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 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. .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) 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, it is not possible to specify arbitrary directory names. A non-standard directory is allowed only if the name is listed in the standard \fBmain.cf\fR file, in the \fBalternate_config_directories\fR configuration parameter value. Only the superuser is allowed to specify arbitrary directory names. .SH FILES .na .nf /var/spool/postfix, mail queue /etc/postfix, configuration files .SH CONFIGURATION PARAMETERS .na .nf .ad .fi See the Postfix \fBmain.cf\fR file for syntax details and for default values. Use the \fBpostfix reload\fR command after a configuration change. .IP \fBimport_environment\fR List of names of environment parameters that can be imported from non-Postfix processes. .IP \fBqueue_directory\fR Top-level directory of the Postfix queue. This is also the root directory of Postfix daemons that run chrooted. .SH SEE ALSO .na .nf sendmail(1) compatibility interface syslogd(8) system logging .SH LICENSE .na .nf .ad .fi The Secure Mailer license must be distributed with this software. .SH AUTHOR(S) .na .nf Wietse Venema IBM T.J.
