public abstract class Message
extends java.lang.Object
implements Part

An abstract mail message, consisting of headers and content.

A message is retrieved from a folder, and is normally a lightweight object that retrieves its properties on demand. Fetch profiles may be used to prefetch certain properties of a message.

To send a message, an appropriate subclsass is instantiated, its properties set, and it is then delivered via a transport using the Transport.sendMessage method.
