NAME

       postdrop - Postfix mail posting utility

SYNOPSIS

       postdrop [-rv] [-c config_dir]

DESCRIPTION

       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 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.

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 connect 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:

              ·      The   name   is   listed   in   the   standard   main.cf   file   with   the
                     alternate_config_directories configuration parameter.

              ·      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 postconf(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)
              The mail system name that is prepended to the process name in  syslog  records,  so
              that "smtpd" becomes, for example, "postfix/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).

FILES

       /var/spool/postfix/maildrop, maildrop queue
