POSTLOG(1)             DragonFly General Commands Manual            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.

       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.

SECURITY
       The postlog(1) command is designed to run with set-groupid privileges,
       so that it can connect to the postlogd(8) daemon process (Postfix 3.7
       and later; earlier implementations of this command must not have
       set-groupid or set-userid permissions).

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 variables 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.
