POSTDROP(1)                            General Commands Manual                           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 in‐
       put to the file.

       Options:

       -c config_dir
              The main.cf configuration file is in the named directory instead of the  default  con‐
              figuration 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) or
       postlogd(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 privi‐
              leges, a non-standard directory is allowed only if:

              •      The  name  is listed in the standard main.cf file with the alternate_config_di‐‐
                     rectories 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 (in the case of sendmail(1), with the  "-C"  op‐
              tion), 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 privileged Postfix process will import from
              a non-Postfix parent process, or name=value environment overrides.

       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)
              A prefix that is prepended to the process name in syslog records, so that,  for  exam‐
              ple, "smtpd" becomes "prefix/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).

       Available in Postfix version 3.6 and later:

       local_login_sender_maps (static:*)
              A  list  of  lookup tables that are searched by the UNIX login name, and that return a
              list of allowed envelope sender patterns separated by space or comma.

       empty_address_local_login_sender_maps_lookup_key (<>)
              The lookup key to be used in  local_login_sender_maps  tables,  instead  of  the  null
              sender address.

       recipient_delimiter (empty)
              The  set  of  characters that can separate an email address localpart, user name, or a
              .forward file name from its extension.

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