<h2><a name="Apache_James_Project"></a>Apache James Project</h2>
<p>James has a modular architecture based on a rich set of modern and efficient components which provides at the end, complete, stable, secure and extendable Mail Servers running on the JVM.
James is made of <b>internal projects</b> - Server, Mailet, Mailbox, Protocols, MPT - and of <b>external projects</b> &#x2013; Hupa, Mime4J, jSieve, jSPF, jDKIM.</p>

<h3><a name="Software_Components"></a>Software Components</h3>
<p>Developers looking for a modular mail platform on which to build can look
at the modules and libraries used to compose James Server 3.0.</p>
<section>
<h4><a name="Internal_Projects"></a>Internal Projects</h4>
<p>The <a class="externalLink" href="http://james.apache.org/mailet/">Apache James Mailet project</a> collects products
related to mailets (mail processing components analogous to servlets). These are independent of the
<a class="externalLink" href="http://james.apache.org/server/">James server</a> and can be reused in any mailet container.</p>
<ul>
<li>The <a class="externalLink" href="http://james.apache.org/mailet/api">Apache James Mailet API</a> specifies mailets.</li>
<li>The <a class="externalLink" href="http://james.apache.org/mailet/base">Apache James Mailet Basic Toolkit</a>
collects utilities and lightweight frameworks useful to develop and test mailets.</li>
<li><a class="externalLink" href="http://james.apache.org/mailet/standard">Apache James Standard Mailets</a> collects
general processing mailets with limited dependencies.</li>
<li><a class="externalLink" href="http://james.apache.org/mailet/crypto">Apache James Crypto Mailets</a> collects
mailets which perform cryptographic processing such as signing, encrypting,
decrypting and signature verification.</li>
</ul>
<p><a class="externalLink" href="http://james.apache.org/protocols/">Apache James Protocols</a> project delivers a lightweight,
and highly extensible framework for mail protocols implementations.
Protocols is coming with several implementations of popular mail protocols like:
</p>
<ul>
<li>SMTP</li>
<li>LMTP</li>
<li>POP3</li>
<li>IMAP</li>
<li>ManageSieve</li>
<li>JMAP</li>
</ul>
<p><a class="externalLink" href="http://james.apache.org/mailbox/">Apache James Mailbox</a> features include the support of emails storage,
indexing emails for research, quotas, an events system.</p>
</section><section>
<h4><a name="External_Projects"></a>External Projects</h4>
<p><a class="externalLink" href="http://james.apache.org/mime4j/">Apache James Mime4J</a> parses MIME typed documents (including
- but not limited to - mail). APIs similar to DOM, SAX and pull parsers are exposed.</p>
<p><a class="externalLink" href="http://james.apache.org/jspf/">Apache James jSPF</a> implements <abbr title="Sender Policy Framework">
<a class="externalLink" href="http://www.openspf.org/">SPF</a></abbr>.
The jSPF library is pure Java SPF implementation. It was designed to match the current SPF-Specs of 2006-2009 (See RFC section).
SPF is also knows as Sender Policy Framework. It was designed to detect email spoofing
This is the solution if you ever was tired of getting spam from yourself.
For more information see <abbr title="Sender Policy Framework"> <a class="externalLink" href="http://www.openspf.org/">openspf website</a></abbr>.
</p>
<p><a class="externalLink" href="http://james.apache.org/jsieve">Apache James jSieve</a> is a Java implementation of
the Sieve mail filtering language defined by <a class="externalLink" href="http://www.ietf.org/rfc/rfc3028.txt">RFC 3028</a>.
jSieve is implemented as a language processor that can be plugged into any internet mail application to add Sieve support.</p>
<p><a class="externalLink" href="http://james.apache.org/jdkim/">Apache James jDKIM</a> implements <abbr title="Domain Keys Identified Mail">
<a class="externalLink" href="http://www.dkim.org/">DKIM</a></abbr>. jDKIM is a DKIM implementation library written in Java. It provides both verification
and signing and also provides Mailets for the Apache JAMES project.
</p>
<p><a class="externalLink" href="http://james.apache.org/mpt/">Apache James MPT</a> is a scripted functional test tool
suitable for testing mail protocols.</p>
