POSTDROP(1)                                                        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
              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 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, it is not possible to specify arbi-
              trary directory names.

              A non-standard directory is allowed only if the name  is  listed
              in  the  standard main.cf file, in the alternate_config_directo-
              ries configuration parameter value.

              Only the superuser 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.
