                          Version:  2.4.x

This is a release of the 2.4.x version of hypermail.

Hypermail is a program that takes a file of mail messages in UNIX mailbox
format and generates a set of cross-referenced HTML documents. 

   Do not put hypermail's output anyplace where a web server might have 
   server side includes (SSI) enabled unless you are sure you know what 
   you are doing. 

   There once existed a program call "mail" that came with hypermail.
   'mail' utility has not installed by default for the last two years.  
   This program has been disabled because it was probably easy for spammers 
   to use as an open relay. It also had problems with enabling malicious 
   use of JavaScript and CRLF Injection.  The 'mail' utility is a historic 
   reclic and will not be supplied in future versions.  Its functionality 
   has been replaced with a warning that anyone using it should remove it 

See the INSTALL file to get started. For a description of how to use it,
see the hypermail.html, hmrc.html, and hypermail-faq.html files that come
in the docs/ directory.
Please refer to Changelog for the list of recent changes.

Hypermail is distributed under the GNU GPL license (see the file COPYING for
details). Some programs that are distributed with it in the archive and
contrib directories have different licenses - check the individual files for

Hypermail Background:

Hypermail was originally designed and developed by Tom Gruber for
Enterprise Integration Technologies (EIT) using Common Lisp. 

It was later rewritten in C by Kevin Hughes in 1994 while Kevin 
worked at EIT. 

License Evolution:

In the spring of 1997, Kevin Hughes heavily pressed Hewlett-Packard
(who was now the legal owner of Hypermail, since EIT was bought by
VeriFone, which was bought by Hewlett-Packard) into placing a free
software license onto his old EIT software.  They officially put the
GNU GPL license on *all* of Kevin's old EIT software, opening it up to
more open methods of development and distribution. So now Hypermail
is under GPL.

EIT's net.disappearance:

A very old and established government contractor company called 
Electronic Instrumentation and Technology Inc. made legal moves to 
obtain the domain. Since VeriFone/HP had no interest in keeping 
EIT, dissolved it completely.  As this company had a trademark on EIT, 
the domain name was given to them. Elizabeth Batson of EIT/VeriFone/HP 
informed Kevin he could maintain all his old software himself wherever 
he wished to put it.

Kevin and ongoing Hypermail Development:

Kevin left Hewlett-Packard in 1997 and helped form a new company 
called Veo Systems ( with his old boss Marty 
Tenenbaum, who founded EIT. Kevin did not have the time to maintain 
any of his old software, so he was looking for different parties to 
help maintain it and take over different pieces. For instance, Getstats 
has been obsoleted by Analog ( 
SWISH has been taken over by the SWISH-E project 
( and many people have been doing 
good things with it.  April 17, 1998 Kevin passed hypermail development 
to Kent Landfield ( Kent had been 
supporting an enhanced version of hypermail he had been using for the 
last few years. It has gradually become a group effort, with Peter McCluskey
<> often acting as the leader during its heydays. 
Since a couple of years, it is stable and mostly unmaintained. W3C continues
to contribute to this repository, although infrequently, sharing with the
community enhancements and bug fixes originating from its use of


This version has been tested on the platforms listed below. If you would 
like to send portability patches or confirmation that it works on a certain
platform, please do.  There should not be toooo many changes that need to be 

This version of hypermail has substantial support for attachments and for
splitting archives into subdirectories. It also allows an administrator to
customize the header and footers to match their local needs.  This allows
you to have hypermail facilities better integrated into your web site. 

This version is an integration of patches that Kevin had received through
the years, and new features through the individual efforts many people.  
This has been run through lint, Insight and Purify and has been cleaned up 

   * archive - general archive utilites that are useful in managing
               list archives. Much of the functionality here has been
               rendered obsolete by the folder_by_date option.
