POSTDROP(1)                                                        POSTDROP(1)



NAME
       postdrop - Postfix mail(1,8) posting utility

SYNOPSIS
       postdrop [-rv] [-c config_dir]

DESCRIPTION
       The  postdrop(1)  command  creates a file(1,n) in(1,8) the maildrop directory and
       copies its standard input to the file.

       Options:

       -c config_dir
              The main.cf configuration file(1,n) is in(1,8) the named(5,8) 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.

SECURITY
       The command is designed to run with set-group ID privileges, so that it
       can write(1,2) to the maildrop queue(1,3) directory and so that it can connect to
       Postfix daemon processes.

DIAGNOSTICS
       Fatal  errors:  malformed input, I/O error(8,n), out of memory. Problems are
       logged to syslogd(8) and to the standard error(8,n) stream.  When the  input
       is  incomplete,  or  when the process receives a HUP, INT, QUIT or TERM
       signal(2,7), the queue(1,3) file(1,n) 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(1,8) the standard main.cf file(1,n) 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 pro-
       gram.  The text below provides only  a  parameter  summary.  See  post-
       conf(3,5)(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(1,5) -d' output)
              The  default  location of the Postfix main.cf and master.cf con-
              figuration files.

       import_environment (see 'postconf(1,5) -d' output)
              The list of environment parameters that a Postfix  process  will
              import from a non-Postfix parent process.

       queue_directory (see 'postconf(1,5) -d' output)
              The location of the Postfix top-level queue(1,3) directory.

       syslog_facility (mail(1,8))
              The syslog(2,3,5,3 Sys::Syslog) facility of Postfix logging.

       syslog_name (postfix)
              The  mail(1,8)  system  name that is prepended to the process name in(1,8)
              syslog(2,3,5,3 Sys::Syslog) records, so that "smtpd"  becomes,  for  example,  "post-
              fix/smtpd".

       trigger_timeout (10s)
              The  time(1,2,n)  limit  for sending a trigger to a Postfix daemon (for
              example, the pickup(8) or qmgr(8) daemon).

       Available in(1,8) Postfix version(1,3,5) 2.2 and later:

       authorized_submit_users (static:anyone)
              List of users(1,5) who are authorized to submit mail(1,8) with  the  send-
              mail(1,8)(1) command (and with the privileged postdrop(1) helper com-
              mand).

FILES
       /var/spool/postfix/maildrop, maildrop queue(1,3)
