NAME
postlogd
-
Postfix internal log server
SYNOPSIS
postlogd [generic Postfix daemon options]
DESCRIPTION
This program logs events on behalf of Postfix programs
when the maillog_file configuration parameter specifies a
non-empty value.
BUGS
Non-daemon Postfix programs don't know that they should log
to the internal logging service before they have processed
command-line options and main.cf parameters. These programs
still log earlier events to the syslog service.
If Postfix is down, the non-daemon programs postfix(1),
postsuper(1), postmulti(1), and postlog(1),
will log directly to $maillog_file. These programs
expect to run with root privileges, for example during
Postfix start-up, reload, or shutdown.
Other non-daemon Postfix programs will never write directly to
$maillog_file (also, logging to stdout would interfere
with the operation of some of these programs). These programs
can log to postlogd(8) if they are run by the super-user,
or if their executable file has set-gid permission. Do not
set this permission on programs other than postdrop(1),
postqueue(1) and (Postfix >= 3.7) postlog(1).
CONFIGURATION PARAMETERS
Changes to
main.cf are not picked up automatically,
because
postlogd(8) terminates only after reaching
the
max_idle time limit.
Use the command "
postfix reload" to speed up a change.
The text below provides only a parameter summary. See
postconf(5) for more details including examples.
- config_directory (see 'postconf-d' output)
-
The default location of the Postfix main.cf and master.cf
configuration files.
- maillog_file (empty)
-
The name of an optional logfile that is written by the Postfix
postlogd(8) service.
- process_id (read-only)
-
The process ID of a Postfix command or daemon process.
- process_name (read-only)
-
The process name of a Postfix command or daemon process.
- syslog_name (see 'postconf-d' output)
-
A prefix that is prepended to the process name in syslog
records, so that, for example, "smtpd" becomes "prefix/smtpd".
- service_name (read-only)
-
The master.cf service name of a Postfix daemon process.
- postlogd_watchdog_timeout (10s)
-
How much time a postlogd(8) process may take to process a request
before it is terminated by a built-in watchdog timer.
Available in Postfix 3.9 and later:
- maillog_file_permissions (0600)
-
The file access permissions that will be set when the file
$maillog_file is created for the first time, or when the file is
created after an existing file is rotated.
