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.

       By  default, logging is sent to syslogd(8) or postlogd(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 (obsolete)
              Include  the  process ID in the logging tag. This flag is ignored as of Postfix 3.4, where the PID
              is always included.

       -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".

       Available in Postfix 3.4 and later:

       maillog_file (empty)
              The name of an optional logfile that is written by the Postfix postlogd(8) service.

       postlog_service_name (postlog)
              The name of the postlogd(8) service entry in master.cf.
