| <h2><a name="IMAP4_Configuration"></a>IMAP4 Configuration</h2> |
| |
| |
| <p>Consult <a class="externalLink" href="https://github.com/apache/james-project/blob/master/server/apps/distributed-app/sample-configuration/imapserver.xml">imapserver.xml</a> in GIT to get some examples and hints.</p> |
| |
| |
| <p>The IMAP4 service is controlled by a configuration block in the imap4server.xml. |
| The imap4server tag defines the boundaries of the configuration block. It encloses |
| all the relevant configuration for the IMAP4 server. The behavior of the IMAP4 service is |
| controlled by the attributes and children of this tag.</p> |
| |
| |
| <p>This tag has an optional boolean attribute - <b>enabled</b> - that defines whether the service is active or not. The value defaults to "true" if |
| not present.</p> |
| |
| |
| <p>The standard children of the imapserver tag are:</p> |
| |
| |
| <dl> |
| |
| <dt><b>bind</b></dt> |
| |
| <dd>Configure this to bind to a specific inetaddress. This is an optional integer value. This value is the port on which this IMAP4 server is configured |
| to listen. If the tag or value is absent then the service |
| will bind to all network interfaces for the machine If the tag or value is omitted, the value will default to the standard IMAP4 port |
| port 143 is the well-known/IANA registered port for IMAP |
| port 993 is the well-known/IANA registered port for IMAPS ie over SSL/TLS</dd> |
| |
| <dt><b>connectionBacklog</b></dt> |
| |
| <dd>Number of connection backlog of the server (maximum number of queued connection requests)</dd> |
| |
| <dt><b>compress</b></dt> |
| |
| <dd>true or false - Use or don't use COMPRESS extension.</dd> |
| |
| <dt><b>maxLineLength</b></dt> |
| |
| <dd>Maximal allowed line-length before a BAD response will get returned to the client |
| This should be set with caution as a to high value can make the server a target for DOS (Denial of Service)!</dd> |
| |
| |
| <dt><b>inMemorySizeLimit</b></dt> |
| |
| <dd>Optional. Size limit before we will start to stream to a temporary file. |
| Defaults to 10MB. Must be a positive integer, optionally with a unit: B, K, M, G.</dd> |
| |
| <dt><b>literalSizeLimit</b></dt> |
| |
| <dd>Optional. Maximum size of a literal (IMAP APPEND). |
| Defaults to 0 (unlimited). Must be a positive integer, optionally with a unit: B, K, M, G.</dd> |
| |
| <dt><b>jmxName</b></dt> |
| |
| <dd>The name given to the configuration</dd> |
| |
| <dt><b>tls</b></dt> |
| |
| <dd>Set to true to support STARTTLS or SSL for the Socket. |
| To use this you need to copy sunjce_provider.jar to /path/james/lib directory. To create a new keystore execute: |
| keytool -genkey -alias james -keyalg RSA -storetype PKCS12 -keystore /path/to/james/conf/keystore<br /> |
| Please note that each IMAP server exposed on different port can specify its own keystore, independently from any other |
| TLS based protocols.</dd> |
| |
| <dt><b>handler.helloName</b></dt> |
| |
| <dd>This is the name used by the server to identify itself in the IMAP4 |
| protocol. If autodetect is TRUE, the server will discover its |
| own host name and use that in the protocol. If discovery fails, |
| the value of 'localhost' is used. If autodetect is FALSE, James |
| will use the specified value.</dd> |
| |
| <dt><b>handler.connectiontimeout</b></dt> |
| |
| <dd>Connection timeout in secconds</dd> |
| |
| <dt><b>handler.connectionLimit</b></dt> |
| |
| <dd>Set the maximum simultaneous incoming connections for this service</dd> |
| |
| <dt><b>handler.connectionLimitPerIP</b></dt> |
| |
| <dd>Set the maximum simultaneous incoming connections per IP for this service</dd> |
| |
| <dt><b>handler.handlerchain</b></dt> |
| |
| <dd>This loads the core CommandHandlers. Only remove this if you really |
| know what you are doing</dd> |
| |
| <dt><b>plainAuthDisallowed</b></dt> |
| |
| <dd>Whether to enable Authentication PLAIN if the connection is not encrypted via SSL or STARTTLS. Defaults to true.</dd> |
