It probably does not work on Windows, although it's possible you could get it running on a Cygwin system (please <a href="mailto:mailman-developers@python.org">let the developer community know</a> if you have success with this!) <p>Before you can run Mailman, you need to make sure that <a href="http://www.python.org/">Python</a> is installed. Mailman 2.1 requires at least Python 2.1.3, although Python 2.2.2 is recommended. Most GNU/Linux systems come with Python pre-installed, so you just need to make sure you're running an up-to-date version. You can do this by executing the following at your shell's command line: <blockquote> <pre> % python -V Python 2.1.3 </pre> </blockquote> If your Python executable doesn't understand the <code>-V</code> option, it's definitely too old! <p>You will also need an SMTP server (a.k.a. mail transport agent or <em>MTA</em>) for mail delivery and reception. Mailman should work well with any of the most popular Unix mail servers such as <a href="http://www.postfix.org/">Postfix</a>, <a href="http://www.exim.org/">Exim</a>, <a href="http://www.sendmail.org/">Sendmail</a> and <a href="http://www.qmail.org/">qmail</a>. <p>You will also need a web server. <a href="http://www.apache.org/">Apache</a> is certainly the most popular, is available for all Unix systems, and works great with Mailman. <p>To install Mailman from the sources, you will also need an ANSI C compiler. The <a href="http://www.gnu.org/software/gcc/">GNU C compiler</a> gcc 2.8.1 or later is known to work well.
