##### Overview

The  postfix-logwatch(1) utility is a Postfix MTA log parser, that pro-
duces summaries, details, and statistics  regarding  the  operation  of
Postfix.

This utility can be used as a standalone program, or as a Logwatch fil-
ter module to produce Postfix summary and detailed reports from  within
Logwatch.

A key feature of postfix-logwatch is its ability to produce a very wide
range of reports with data grouped and sorted as much  as  possible  to
reduce  noise  and highlight patterns.  Brief summary reports provide a
quick overview of general  Postfix  operations  and  message  delivery,
calling out warnings that may require attention.  Detailed reports pro-
vide easy to scan, hierarchically-arranged and  organized  information,
with as much or little detail as desired.

##### Installation: standalone

The included Makefile will install the postfix-logwatch utility
for you.  Run:

    make install-standalone

to install the utility and its configuration file.  Installation
will default to /usr/local/bin and /usr/local/etc, respectively.
 
##### Installation: logwatch

To use postfix-logwatch as a logwatch script, the files:
 
    postfix-logwatch
    postfix-logwatch.conf
 
will need to be installed into one of logwatch's known directories.
To avoid overwriting your existing default logwatch filter files,
the enclosed files can be installed into the global logwatch
installation directory, which is typically:

   /etc/logwatch

The included Makefile can be used to install the files into
/etc/logwatch for you. To install the filter into an existing
logwatch installation, run:

    make install-logwatch

NOTE: the files postfix-logwatch and postfix-logwatch.conf must be
renamed (by removing the "-logwatch" suffix), for logwatch to
function correctly.  The Makefile takes care of this.  The
Makefile also disables perl's taint mode (-T) when running under
logwatch.  If you install the files manually, be sure to remove
the -T from the first line of the postfix filter.

For non-standard installations, you will need to determine your
global logwatch directory, and define "prefix" in the attached
Makefile.

Alternatively, you can manually copy the files to their proper
locations:

    cp postfix-logwatch       /etc/logwatch/scripts/services/postfix
    cp postfix-logwatch.conf  /etc/logwatch/conf/services/postfix.conf
    [ remove -T from line 1 of /etc/logwatch/scripts/services/postfix ]

    Optional:
    cp postfix-logwatch.1     /usr/local/man/man1/postfix-logwatch.1

##### Usage

The postfix-logwatch utility is used standalone as:

   postfix-logwatch /path/to/maillog

For brief help:

   postfix-logwatch --help

To use within logwatch:

   logwatch --service postfix ...

See the postfix-logwatch(1) man page for complete details, and
see comments in the postfix-logwatch.conf file for additional
information.
