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 direc-
       tory 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 sta-
              tus  information  on  standard output. This is cur-
              rently the only supported method.

       -v     Enable verbose logging for debugging purposes. Mul-
              tiple  -v  options  make  the software increasingly
              verbose.

SECURITY
       The command is designed to run with  set-group  ID  privi-
       leges,  so  that it can write to the maildrop queue direc-
       tory and so that it can connect  to  Postfix  daemon  pro-
       cesses.

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 parame-
              ter 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.
