PROGRAM:
NAME
postlog - Postfix-compatible logging utility
SYNOPSIS
postlog [-iv] [-c config_dir] [-p priority] [-t tag] [text...]
DESCRIPTION
The postlog(1) command implements a Postfix-compatible logging interface for use in, for
example, shell scripts.
By default, postlog(1) logs the text given on the command line as one record. If no text
is specified on the command line, postlog(1) reads from standard input and logs each input
line as one record.
Logging is sent to syslogd(8); when the standard error stream is connected to a terminal,
logging is sent there as well.
The following options are implemented:
-c config_dir
Read the main.cf configuration file in the named directory instead of the default
configuration directory.
-i Include the process ID in the logging tag.
-p priority (default: info)
Specifies the logging severity: info, warn, error, fatal, or panic. With Postfix
3.1 and later, the program will pause for 1 second after reporting a fatal or panic
condition, just like other Postfix programs.
-t tag Specifies the logging tag, that is, the identifying name that appears at the
beginning of each logging record. A default tag is used when none is specified.
-v Enable verbose logging for debugging purposes. Multiple -v options make the
software increasingly verbose.
ENVIRONMENT
MAIL_CONFIG
Directory with the main.cf file.
CONFIGURATION PARAMETERS
The following main.cf parameters are especially relevant to this program.
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.
syslog_facility (mail)
The syslog facility of Postfix logging.
syslog_name (see 'postconf -d' output)
The mail system name that is prepended to the process name in syslog records, so
that "smtpd" becomes, for example, "postfix/smtpd".
