postdrop - Postfix mail posting utility
postdrop [-rv] [-c config_dir]
The postdrop(1) command creates a file in the maildrop directory and
copies its standard input to the file.
The main.cf configuration file is in the named directory instead
of the default configuration directory. See also the MAIL_CONFIG
environment setting below.
-r 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.
-v Enable verbose logging for debugging purposes. Multiple -v
options make the software increasingly verbose. As of Postfix
2.3, this option is available for the super-user only.
The command is designed to run with set-group ID privileges, so that it
can write to the maildrop queue directory and so that it can connect to
Postfix daemon processes.
Fatal errors: malformed input, I/O error, out of memory. Problems are
logged to syslogd(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.

of set-group ID privileges, a non-standard directory is allowed
