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.

       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  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.

       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.
