    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 inter-
           face 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  con-
           nected 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  pro-
           gram.

           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  con-
                  figuration 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,  "post-
                  fix/smtpd".
