MultipartDataSource: MultipartDataSource is a `DataSource` that contains body parts.
Part: The `Part` interface is the common base interface for Messages and BodyParts.
UIDFolder: The `UIDFolder` interface is implemented by Folders that can support the "disconnected" mode of operation, by providing unique-ids for messages in the folder.

Class Summary
Address: This abstract class models the addresses in a message.
Authenticator: The class Authenticator represents an object that knows how to obtain authentication for a network connection.
BodyPart: This class models a Part that is contained within a Multipart.
FetchProfile: Clients use a FetchProfile to list the Message attributes that it wishes to prefetch from the server for a range of messages.
FetchProfile.Item: This inner class is the base class of all items that can be requested in a FetchProfile.
Flags: The Flags class represents the set of flags on a Message.
Flags.Flag: This inner class represents an individual system flag.
Folder: Folder is an abstract class that represents a folder for mail messages.
Header: The Header class stores a name/value pair to represent headers.
Message: This class models an email message.
Message.RecipientType: This inner class defines the types of recipients allowed by the Message class.
MessageContext: The context in which a piece of Message content is contained.
Multipart: Multipart is a container that holds multiple body parts.
PasswordAuthentication: The class PasswordAuthentication is a data holder that is used by Authenticator.
Provider: The Provider is a class that describes a protocol implementation.
Provider.Type: This inner class defines the Provider type.
Service: An abstract class that contains the functionality common to messaging services, such as stores and transports.
Session: The Session class represents a mail session and is not subclassed.
Store: An abstract class that models a message store and its access protocol, for storing and retrieving messages.
Transport: An abstract class that models a message transport.
UIDFolder.FetchProfileItem: A fetch profile item for fetching UIDs.
URLName: The name of a URL.

AuthenticationFailedException: This exception is thrown when the connect method on a Store or Transport object fails due to an authentication failure (e.g., bad user name or password).
FolderClosedException: This exception is thrown when a method is invoked on a Messaging object and the Folder that owns that object has died due to some reason.
FolderNotFoundException: This exception is thrown by Folder methods, when those methods are invoked on a non existent folder.
IllegalWriteException: The exception thrown when a write is attempted on a read-only attribute of any Messaging object.
MessageRemovedException: The exception thrown when an invalid method is invoked on an expunged Message.
MessagingException: The base class for all exceptions thrown by the Messaging classes
MethodNotSupportedException: The exception thrown when a method is not supported by the implementation
NoSuchProviderException: This exception is thrown when Session attempts to instantiate a Provider that doesn't exist.
ReadOnlyFolderException: This exception is thrown when an attempt is made to open a folder read-write access when the folder is marked read-only.
