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.

       import_environment (see 'postconf -d' output)
              The  list  of  environment parameters that a privileged Postfix process will import
              from a non-Postfix parent process, or name=value environment overrides.

       syslog_facility (mail)
              The syslog facility of Postfix logging.

       syslog_name (see 'postconf -d' output)
              A prefix that is prepended to the process name in  syslog  records,  so  that,  for
              example, "smtpd" becomes "prefix/smtpd".
