Mailman is integrated with the web, making it easy for users to manage their accounts and for list owners to administer their lists. Mailman supports built-in archiving, automatic bounce processing, content filtering, digest delivery, spam filters, and more. See the <a href="features.html">features page</a> for details. <p>Mailman is free software, distributed under the <a href="http://www.gnu.org/copyleft/gpl.html">GNU General Public License</a>. Mailman is written in the <a href="http://www.python.org/">Python</a> programming language, with a little bit of C code for security. <p>The name of this software is spelled <em>Mailman</em> with a capital leading <em>M</em> and a lowercase second <em>m</em>. It is incorrect to spell it "MailMan" (i.e. you should not use StudlyCaps). <p>See the <a href="security.html">Security page</a> for important security related information, including critical patches and contact information for reporting suspected security vulnerabilities. <h3>Current Version</h3> The current stable GNU Mailman version is 2.1.5, released on 15-May-2004.
