POSTDROP(1)                                                        POSTDROP(1)



NAME
       postdrop - Postfix mail posting utility

SYNOPSIS
       postdrop [-rv] [-c configdir]

DESCRIPTION
       The  postdrop  command  creates  a  file  in the maildrop directory and
       copies its standard input to the file.

       Options:

       -c configdir
              The main.cf configuration file is in the named directory instead
              of the default configuration directory. See also the MAILCONFIG
              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
       MAILCONFIG
              Directory with the main.cf file. In order to avoid  exploitation
              of  set-group ID privileges, a non-standard directory is allowed
              only if:

              ]o      The name is listed in the standard main.cf file with  the
                     alternateconfigdirectories configuration parameter.

              ]o      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(5) for more details including examples.

       alternateconfigdirectories (empty)
              A list of non-default Postfix configuration directories that may
              be specified with "-c configdirectory" on the command line,  or
              via the MAILCONFIG environment parameter.

       configdirectory (see ''postconf -d'' output)
              The  default  location of the Postfix main.cf and master.cf con-
              figuration files.

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

       queuedirectory (see ''postconf -d'' output)
              The location of the Postfix top-level queue directory.

       syslogfacility (mail)
              The syslog facility of Postfix logging.

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

       triggertimeout (100s)
              The  time  limit  for sending a trigger to a Postfix daemon (for
              example, the pickup(8) or qmgr(8) daemon).

FILES
       /var/spool/postfix/maildrop, maildrop queue
