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".
