    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 (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".
