SpamAssassin sports new open-source license

Story last modified September 22, 2004, 5:44 PM PDT
Programmers on Wednesday released the new version 3.0 of SpamAssassin,
open-source software for filtering out unwanted e-mail, but the changes are
as much legal as technological.
Project leaders for the widely used software chose to enter the fold of the
Apache Software Foundation to take advantage of the nonprofit group's legal
and technical resources. To make the move, SpamAssassin
eId=3&oId=2102-7344_3-5378375&ontId=7343&lop=nl_ex> had to adopt the Apache
CENSE-2.0&siteId=3&oId=2102-7344_3-5378375&ontId=7343&lop=nl_ex> License.
Previously, the software was available under a choice of two licenses: the
General
tml&siteId=3&oId=2102-7344_3-5378375&ontId=7343&lop=nl_ex> Public License
(GPL) that governs Linux and many other open-source programs and the Perl
Artistic License.
Open-source software advocates tout the fact that their programming
philosophy permits large numbers of people to contribute to a project. But
making the license change illustrated a difficulty of that broad
collaboration: Project leaders had to secure the permission from all
programmers who had contributed to SpamAssassin.
"It was fairly difficult and took us about four months to do the brunt of
the work," Dan Quinlan, one of the lead programmers, said via e-mail. "We
had to contact about 100 contributors, get their explicit permission to
relicense the code, and in some cases where we could not contact a
contributor, we had to remove their code and reimplement it."
The work was worth it, though, he said. The previous dual-license situation
was confusing for handling software contributions, and the Apache License
has "some nice and very reasonable properties," Quinlan said. "For example,
if someone contributes code that is itself encumbered by their own patent,
they can't later sue us over it."
Apache
5.html?tag=nl> is the most widely used software for hosting Web sites, with
68
Fweb_server_survey.html&siteId=3&oId=2102-7344_3-5378375&ontId=7343&lop=nl_e
x> percent market share, according to monitoring firm NetCraft. The Apache
3-227965.html?tag=nl> Software Foundation is broader, though, governing
several projects including software to process XML messages and run Java
programs.
The Apache Software Foundation owns the SpamAssassin source code copyright,
Quinlan said.
Technical changes, too
Version 3.0 of SpamAssassin includes technical changes as well. One major
feature is support for Sender
?tag=nl> Policy Framework (SPF), a mechanism to accurately trace e-mail
origins to help identify possible spam
l> .
Apache has rejected a broader proposal called Sender
3_3-5345317.html?tag=nl> ID that incorporates SPF and a comparable Microsoft
technology called Caller
32_3-5220253.html?tag=nl> ID for E-mail. Apache objected to Microsoft's
licensing terms.
The new SpamAssassin also has a more modular design intended to let others
add new features more easily.
"It makes it really easy to integrate new antispam techniques and other
features into SpamAssassin," Quinlan said. "We hope this will result in the
much wider proliferation of third-party add-ons, and we expect the best of
those to be contributed and added to future SpamAssassin releases."
SpamAssassin is used
6751.html?tag=nl> in McAfee's SpamKiller software.
