    POSTLOG(1)                                                          POSTLOG(1)

    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
                  Specifies the  logging  severity:  info  (default),
                  warn, error, fatal, or panic.

           -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 speci-
                  fied.

           -v     Enable verbose logging for debugging purposes. Mul-
                  tiple  -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 (postfix)
                  The  mail  system  name  that  is  prepended to the
                  process name in syslog  records,  so  that  "smtpd"
                  becomes, for example, "postfix/smtpd".
