POSTDROP(1)						      General Commands Manual						       POSTDROP(1)

NAME
postdrop - Postfix mail posting utility SYNOPSIS
postdrop [-rv] [-c config_dir] DESCRIPTION
The postdrop command creates a file in the maildrop directory and copies its standard input to the file. Options: -c 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 out- put. This is currently the only supported method. -v Enable verbose logging for debugging purposes. Multiple -v options make the software increasingly verbose. SECURITY
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 con- nect to Postfix daemon processes. DIAGNOSTICS
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. ENVIRONMENT
MAIL_CONFIG Directory with the main.cf 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 main.cf file, in the alternate_config_directories configuration parameter value. Only the super-user is allowed to specify arbitrary directory names. FILES
/var/spool/postfix, mail queue /etc/postfix, configuration files CONFIGURATION PARAMETERS
See the Postfix main.cf file for syntax details and for default values. Use the postfix reload command after a configuration change. import_environment List of names of environment parameters that can be imported from non-Postfix processes. queue_directory Top-level directory of the Postfix queue. This is also the root directory of Postfix daemons that run chrooted. SEE ALSO

The postdrop(1) command creates a file in the maildrop directory and copies its standard input to the file. Options: -c config_dir 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 out- put.

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 con- nect to Postfix daemon processes. DIAGNOSTICS
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. ENVIRONMENT
MAIL_CONFIG Directory with the main.cf file. In order to avoid exploitation of set-group ID privileges, a non-standard directory is allowed only if: o The name is listed in the standard main.cf file with the alternate_config_directories configuration parameter. o The command is invoked by the super-user. CONFIGURATION PARAMETERS
The following main.cf parameters are especially relevant to this program. The text below provides only a parameter summary. See post- conf(5) for more details including examples. alternate_config_directories (empty) A list of non-default Postfix configuration directories that may be specified with "-c config_directory" on the command line, or via the MAIL_CONFIG environment parameter. config_directory (see 'postconf -d' output) The default location of the Postfix main.cf and master.cf configuration files. import_environment (see 'postconf -d' output) The list of environment parameters that a Postfix process will import from a non-Postfix parent process. queue_directory (see 'postconf -d' output) The location of the Postfix top-level queue directory. syslog_facility (mail) The syslog facility of Postfix logging. syslog_name (see 'postconf -d' output) A prefix that is prepended to the process name in syslog records, so that, for example, "smtpd" becomes "prefix/smtpd". trigger_timeout (10s) The time limit for sending a trigger to a Postfix daemon (for example, the pickup(8) or qmgr(8) daemon). Available in Postfix version 2.2 and later: authorized_submit_users (static:anyone) List of users who are authorized to submit mail with the sendmail(1) command (and with the privileged postdrop(1) helper command).
