| <h2><a name="Servers"></a>Servers</h2> |
| |
| <section> |
| <h3><a name="Introduction"></a>Introduction</h3> |
| |
| |
| <p>Apache James is an open source project intended to produce a robust, flexible, and powerful |
| enterprise class server that provides email and email-related services. It is also designed to |
| be highly customizable, allowing administrators to configure Apache James to process email in a |
| nearly endless variety of fashions.</p> |
| |
| |
| <p>The standard Apache James distribution deploys inside the Spring dependency injection container. |
| In addition to providing a robust server architecture for James, the use of Spring allows Apache James administrators |
| to deploy their own applications inside the container. These applications can then be accessed during |
| mail processing.</p> |
| |
| |
| <p>The Apache James Server is implemented as a complete collection of servers and related components that, taken together, |
| provide an email solution. These components are described below.</p> |
| |
| |
| <p>Note that each protocol can specify its TLS settings and keys in an independent way.</p> |
| |
| </section> |
| |
| <section> |
| <h3><a name="SMTP_Protocol"></a>SMTP Protocol</h3> |
| |
| |
| <p>SMTP (Simple Mail Transport Protocol) is the standard method of sending and delivering |
| email on the internet. Apache James provides a full-function implementation of the SMTP specification, |
| with support for some optional features such as message size limits, SMTP auth, and encrypted |
| client/server communication.</p> |
| |
| |
| <p>More information on configuring the SMTP service can be found <a href="config-smtp-lmtp.html">here</a>.</p> |
| |
| |
| <p>You can find further information about supported protocols and RFCs |
| <a class="externalLink" href="http://james.apache.org/protocols/smtp.html">on the JAMES-PROTOCOLS project SMTP page</a> |
| </p> |
| </section> |
| |
| <section> |
| <h3><a name="IMAP4_Protocol"></a>IMAP4 Protocol</h3> |
| |
| |
| <p>The IMAP4 protocol allows users to retrieve email messages. It is the method |
| most commonly used by email clients to download and manage email messages.</p> |
| |
| |
| <p>The Apache James version of the IMAP4 service is a simple and straightforward implementation that |
| provides full compliance with the specification and maximum compatibility with common |
| IMAP4 clients. In addition, Apache James can be configured to require SSL/TLS connections for |
| IMAP4 client connecting to the server.</p> |
| |
| |
| <p>More information on configuring the IMAP4 service can be found <a href="config-imap4.html">here</a>.</p> |
| |
| |
| <p>You can find further information about supported protocols and RFCs |
| <a class="externalLink" href="http://james.apache.org/protocols/imap4.html">on the JAMES-PROTOCOLS project IMAP4 page</a> |
| </p> |
| |
| |
| <p> |
| Note that MOVE extension (RFC-6851) needs a MailboxManager implementing the move function. For now, this is only done with |
| the CassandraMailboxManager |
| </p> |
| |
| <p> |
| It supports the METADATA extension (RFC-5464): |
| </p> |
| <ul> |
| |
| <li> |
| It does not support the server's metadata so far. |
| </li> |
| |
| <li> |
| It does not support permission on metadata because the ACL extension is not present. |
| </li> |
| |
| <li> |
| The quota limitations on MailboxAnnotations are hardcoded. They concern the number of annotations per mailbox (10), as well as the size of an annotation (1024 bytes) |
| </li> |
| </ul> |
| |
| </section> |
| |
| <section> |
| <h3><a name="POP3_Protocol"></a>POP3 Protocol</h3> |
| |
| |
| <p>The POP3 protocol allows users to retrieve email messages. It is the method |
| most commonly used by email clients to download and manage email messages.</p> |
| |
| |
| <p>The Apache James version of the POP3 service is a simple and straightforward implementation that |
| provides full compliance with the specification and maximum compatibility with common |
| POP3 clients. In addition, Apache James can be configured to require SSL/TLS connections for |
| POP3 client connecting to the server.</p> |
| |
| |
| <p>More information on configuring the POP3 service can be found <a href="config-pop3.html">here</a>.</p> |
| |
| |
| <p>You can find further information about supported protocols and RFCs |
| <a class="externalLink" href="http://james.apache.org/protocols/pop3.html">on the JAMES-PROTOCOLS project POP3 page</a> |
| </p> |
| </section> |
| |
| <section> |
| <h3><a name="FetchMail"></a>FetchMail</h3> |
| |
| |
| <p>FetchMail, unlike the other Apache James components, is not an implementation of an RFC. Instead, it's a |
| component that allows the administrator to configure Apache James to retrieve email from a number of POP3 |
| servers and deliver them to the local spool. This is useful for consolidating mail delivered to a |
| number of accounts on different machines to a single account.</p> |
| |
| |
| <p>More information on configuring FetchMail can be found <a href="config-fetchmail.html">here</a>.</p> |
| |

| <h3><a name="JMX"></a>JMX</h3> |
| |
| |
| <p>JMX (Java Management Extension) is used for the management.</p> |
