6 postlogd - Postfix internal log server
7
9 postlogd [generic Postfix daemon options]
10
12 This program logs events on behalf of Postfix programs when the maillog
13 configuration parameter specifies a non-empty value.
14
16 Non-daemon Postfix programs don't know that they should log to the
17 internal logging service before they have processed command-line
18 options and main.cf parameters. These programs still log earlier events
19 to the syslog service.
20
21 If Postfix is down, the non-daemon programs postfix(1), postsuper(1),
22 postmulti(1), and postlog(1), will log directly to $maillog_file. These
23 programs expect to run with root privileges, for example during Postfix
24 start-up, reload, or shutdown.
25
26 Other non-daemon Postfix programs will never write directly to $mail‐
27 log_file (also, logging to stdout would interfere with the operation of
28 some of these programs). These programs can log to postlogd(8) if they
29 are run by the super-user, or if their executable file has set-gid per‐
30 mission. Do not set this permission on programs other than postdrop(1)
31 and postqueue(1).
32
34 Changes to main.cf are picked up automatically, as postlogd(8) pro‐
35 cesses run for only a limited amount of time. Use the command "postfix
36 reload" to speed up a change.
37
38 The text below provides only a parameter summary. See postconf(5) for
39 more details including examples.
40
41 config_directory (see 'postconf -d' output)
42 The default location of the Postfix main.cf and master.cf con‐
43 figuration files.

50 The process ID of a Postfix command or daemon process.
51
52 process_name (read-only)
53 The process name of a Postfix command or daemon process.
54
55 syslog_name (see 'postconf -d' output)
56 A prefix that is prepended to the process name in syslog
57 records, so that, for example, "smtpd" becomes "prefix/smtpd".
58
59 service_name (read-only)
60 The master.cf service name of a Postfix daemon process.
61
62 postlogd_watchdog_timeout (10s)
63 How much time a postlogd(8) process may take to process a
64 request before it is terminated by a built-in watchdog timer.

67 postconf(5), configuration parameters
68 syslogd(8), system logging
