| <h2><a name="What_is_the_Apache_Mailet_API.3F"></a>What is the Apache Mailet API?</h2> |
| |
| <p> |
| The Apache Mailet API is a Java API which allows the rapid development and flexible deployment of email |
| processing functionality. |
| </p> |
| |
| <p> |
| The Mailet API is a subproject of <a class="externalLink" href="http://james.apache.org">Apache James</a>. |
| All who are interested in developing the Mailet API and James will be warmly |
| welcomed on the <a href="/mail-lists.html">mailing lists</a>. |
| </p> |
| </section> |

| <h3><a name="What_Is_A_Mailet.3F"></a>What Is A Mailet?</h3> |
| |
| <p> |
| A mailet is a mail processing component. Though there are some differences, a servlet as a HTTP |
| processing component is a useful analogy. |
| </p> |
| |
| <p> |
| Mailets implement <a href="/mailet/apidocs/org/apache/mailet/Mailet.html">Mailet</a>. |
| Mailets execute within a mailet container. |
| <a class="externalLink" href="http://james.apache.org/server">James server</a> |
| is a well known mailet container. Assembly and configuration of mailets and mail processors is the |
| responsibility of the particular container. |
| </p> |
| </section><section> |
| <h3><a name="Mailet_Basic_Lifecycle"></a>Mailet Basic Lifecycle</h3> |
| |
| <p> |
| Mailets have a simple lifecycle managed by the mailet container: |
| </p> |
| |
| <ol style="list-style-type: decimal"> |
| |
| <li> |
| <b> |
| init( |
| <a href="apidocs/org/apache/mailet/MailetConfig.html">MailetConfig</a> |
| config) |
| |
| </b> |
| passes environmental information. Any setup necessary should be performed now. |
| </li> |
| |
| <li>During processing, |
| <b> |
| service( |
| <a href="apidocs/org/apache/mailet/Mail.html">Mail</a> |
| mail) |
| |
| </b> |
| is called repeatedly. Note that this method may be called concurrently. |
| </li> |
| |
| <li> |
| <b> |
| destroy() |
| </b> |
| is called when the mailet is taken out of service. |
| </li> |
| </ol> |
| </section> |
| <section> |
| <h3><a name="Configuration"></a>Configuration</h3> |
| |
| <p> |
| <a href="apidocs/org/apache/mailet/MailetConfig.html">MailetConfig</a> |
| gives access to simple parametrization. |
| getInitParameter |
| allows configuration parameters to be passed from the mailet container. |
| How these parameters are set by the user of the mailet is the responsibility of the container. |
| More sophisticated configuration and assembly (for example, allowing access to services) is also |
| the responsibility of the container. |
| </p> |
| </section> |
| <section> |
| <h3><a name="Communication_With_The_Container"></a>Communication With The Container</h3> |
| |
| <p> |
| <a href="apidocs/org/apache/mailet/MailetConfig.html">MailetConfig</a> |
| allows communication with the container |
| by calling getMailetContext(). See |
| <a href="apidocs/org/apache/mailet/MailetContext.html">MailetContext</a> |
| for more details. |
