6 postdrop - Postfix mail posting utility
7
9 postdrop [-rv] [-c config_dir]
10
12 The postdrop(1) command creates a file in the maildrop directory and
13 copies its standard input to the file.
14 Options:
16 -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 -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 -v Enable verbose logging for debugging purposes. Multiple -v
27 options make the software increasingly verbose. As of Postfix
28 2.3, this option is available for the super-user only.
29
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
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
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 · The name is listed in the standard main.cf file with the
48 alternate_config_directories configuration parameter.
49 · The command is invoked by the super-user.
51
53 The following main.cf parameters are especially relevant to this pro‐
54 gram. The text below provides only a parameter summary. See post‐
55 conf(5) for more details including examples.
56 alternate_config_directories (empty)
58 A list of non-default Postfix configuration directories that may
59 be specified with "-c config_directory" on the command line (in
60 the case of sendmail(1), with the "-C" option), or via the
61 MAIL_CONFIG environment parameter.
62 config_directory (see 'postconf -d' output)
64 The default location of the Postfix main.cf and master.cf con‐
65 figuration files.
66 import_environment (see 'postconf -d' output)
68 The list of environment parameters that a privileged Postfix
69 process will import from a non-Postfix parent process, or
70 name=value environment overrides.
71 queue_directory (see 'postconf -d' output)
73 The location of the Postfix top-level queue directory.
74 syslog_facility (mail)
76 The syslog facility of Postfix logging.
77 syslog_name (see 'postconf -d' output)
79 A prefix that is prepended to the process name in syslog
80 records, so that, for example, "smtpd" becomes "prefix/smtpd".
81 trigger_timeout (10s)
83 The time limit for sending a trigger to a Postfix daemon (for
84 example, the pickup(8) or qmgr(8) daemon).
85 Available in Postfix version 2.2 and later:
87 authorized_submit_users (static:anyone)
89 List of users who are authorized to submit mail with the send‐
