org.apache.james.core
Class MailImpl

java.lang.Object
  extended by org.apache.james.core.MailImpl
All Implemented Interfaces:
java.io.Serializable, java.lang.Cloneable, org.apache.avalon.framework.activity.Disposable, Mail

public class MailImpl
extends java.lang.Object
implements org.apache.avalon.framework.activity.Disposable, Mail

Wraps a MimeMessage adding routing information (from SMTP) and some simple API enhancements.

From James version > 2.2.0a8 "mail attributes" have been added. Backward and forward compatibility is supported: messages stored in file repositories without attributes by James version <= 2.2.0a8 will be processed by later versions as having an empty attributes hashmap; messages stored in file repositories with attributes by James version > 2.2.0a8 will be processed by previous versions, ignoring the attributes.
