POSTDROP(1)                                                        POSTDROP(1)

       postdrop - Postfix mail posting utility

       <b>postdrop</b> [<b>-rv</b>] [<b>-c</b> <i>config</i><b>_</b><i>dir</i>]

       The  <a href="postdrop.1.html"><b>postdrop</b>(1)</a>  command  creates  a file in the <b>maildrop</b>
       directory and copies its standard input to the file.


       <b>-c</b> <i>config</i><b>_</b><i>dir</i>
              The <a href="postconf.5.html"><b></b></a> configuration  file  is  in  the  named
              directory  instead  of  the  default  configuration
              directory. See  also  the  MAIL_CONFIG  environment
              setting below.

       <b>-r</b>     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.

       <b>-v</b>     Enable verbose logging for debugging purposes. Mul-
              tiple  <b>-v</b>  options  make  the software increasingly
              verbose. As of Postfix 2.3, this option  is  avail-
              able for the super-user only.

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

       Fatal errors: malformed input, I/O error, out  of  memory.
       Problems  are  logged  to  <b>syslogd</b>(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.

              Directory with the <a href="postconf.5.html"><b></b></a> file. In order to  avoid
              exploitation  of  set-group  ID  privileges, a non-
              standard directory is allowed only if:

              <b>o</b>      The name is listed in the  standard  <a href="postconf.5.html"><b></b></a>
                     file  with  the <b><a href="postconf.5.html#alternate_config_directories">alternate_config_directories</a></b>
                     configuration parameter.

              <b>o</b>      The command is invoked by the super-user.

       The following <a href="postconf.5.html"><b></b></a> parameters are  especially  relevant
       to this program.  The text below provides only a parameter
       summary. See <a href="postconf.5.html"><b>postconf</b>(5)</a> for more details including  exam-
