NAME

6       postdrop - Postfix mail posting utility
7

SYNOPSIS

9       postdrop [-rv] [-c config_dir]
10

DESCRIPTION

12       The  postdrop(1)  command  creates a file in the maildrop directory and
13       copies its standard input to the file.
14
15       Options:
16
17       -c config_dir
18              The main.cf configuration file is in the named directory instead
19              of the default configuration directory. See also the MAIL_CONFIG
20              environment setting below.
21
22       -r     Use a Postfix-internal protocol for  reading  the  message  from
23              standard input, and for reporting status information on standard
24              output. This is currently the only supported method.
25
26       -v     Enable verbose logging for debugging purposes. Multiple  -v  op‐
27              tions make the software increasingly verbose. As of Postfix 2.3,
28              this option is available for the super-user only.
29

SECURITY

31       The command is designed to run with set-group ID privileges, so that it
32       can write to the maildrop queue directory and so that it can connect to
33       Postfix daemon processes.
34

DIAGNOSTICS

36       Fatal errors: malformed input, I/O error, out of memory.  Problems  are
37       logged  to  syslogd(8) or postlogd(8) and to the standard error stream.
38       When the input is incomplete, or when the process receives a HUP,  INT,
39       QUIT or TERM signal, the queue file is deleted.
40

ENVIRONMENT

42       MAIL_CONFIG
43              Directory  with the main.cf file. In order to avoid exploitation
44              of set-group ID privileges, a non-standard directory is  allowed
45              only if:
46
47              •      The  name is listed in the standard main.cf file with the
48                     alternate_config_directories configuration parameter.
49
50              •      The command is invoked by the super-user.
51
