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.


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 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  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.
