postdrop(1)


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
