Description
Interface Summary

MessageAware

An interface optionally implemented by DataSources to
supply information to a DataContentHandler about the
message context in which the data content object is operating.

MultipartDataSource

MultipartDataSource is a DataSource that contains body
parts.

Part

The Part interface is the common base interface for
Messages and BodyParts.

QuotaAwareStore

An interface implemented by Stores that support quotas.

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.

Quota

This class represents a set of quotas for a given quota root.

Quota.Resource

An individual resource in a quota root.

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.

Exception Summary

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.

SendFailedException

This exception is thrown when the message cannot be sent.

StoreClosedException

This exception is thrown when a method is invoked on a Messaging object
and the Store that owns that object has died due to some reason.

Package javax.mail Description
The JavaMailTM API
provides classes that model a mail system.
The javax.mail package defines classes that are common to
all mail systems.
The javax.mail.internet package defines classes that are specific
to mail systems based on internet standards such as MIME, SMTP, POP3, and IMAP.
The JavaMail API includes the javax.mail package and subpackages.
For an overview of the JavaMail API, read the JavaMail specification
included in the download bundle or
available on the JavaMail web site.
The code to send a plain text message can be as simple as the following:
    Properties props = new Properties();
    props.put("mail.smtp.host", "my-mail-server");
    props.put("mail.from", "me@example.com");
    Session session = Session.getInstance(props, null);
    try {
        MimeMessage msg = new MimeMessage(session);
        msg.setFrom();
        msg.setRecipients(Message.RecipientType.TO,
                          "you@example.com");
        msg.setSubject("JavaMail hello world example");
        msg.setSentDate(new Date());
        msg.setText("Hello, world!\n");
        Transport.send(msg);
    } catch (MessagingException mex) {
        System.out.println("send failed, exception: " + mex);
    }
The JavaMail download bundle contains many more complete examples
in the "demo" directory.
Don't forget to see the
JavaMail API FAQ
for answers to the most common questions.
The
JavaMail web site
contains many additional resources.
The JavaMail API supports the following standard properties,
which may be set in the Session object, or in the
Properties object used to create the Session object.
The properties are always set as strings; the Type column describes
how the string is interpreted.  For example, use
        props.put("mail.debug", "true");
to set the mail.debug property, which is of type boolean.
Name
Type
Description
mail.debug
boolean
The initial debug mode.
Default is false.
mail.from
String
The return email address of the current user, used by the
InternetAddress method getLocalAddress.
mail.mime.address.strict
boolean
The MimeMessage class uses the InternetAddress method
parseHeader to parse headers in messages.  This property
controls the strict flag passed to the parseHeader
method.  The default is true.
mail.host
String
The default host name of the mail server for both Stores and Transports.
Used if the mail.protocol.host property isn't set.
mail.store.protocol
String
Specifies the default message access protocol.  The
Session method getStore() returns a Store
object that implements this protocol.  By default the first Store
provider in the configuration files is returned.
mail.transport.protocol
String
Specifies the default message access protocol.  The
Session method getTransport() returns a Transport
object that implements this protocol.  By default the first Transport
provider in the configuration files is returned.
mail.user
String
The default user name to use when connecting to the mail server.
Used if the mail.protocol.user property isn't set.
mail.protocol.class
String
Specifies the fully qualified class name of the provider for the
specified protocol.  Used in cases where more than one provider
for a given protocol exists; this property can be used to specify
which provider to use by default.  The provider must still be listed
in a configuration file.
mail.protocol.host
String
The host name of the mail server for the specified protocol.
Overrides the mail.host property.
mail.protocol.port
int
The port number of the mail server for the specified protocol.
If not specified the protocol's default port number is used.
mail.protocol.user
String
The user name to use when connecting to mail servers
using the specified protocol.
Overrides the mail.user property.
The JavaMail API also supports several System properties;
see the
javax.mail.internet
package documentation
for details.
The JavaMail reference
implementation from Sun includes protocol providers in subpackages of
com.sun.mail.  Note that the APIs to these protocol
providers are not part of the standard JavaMail API.  Portable
programs will not use these APIs.
Nonportable programs may use the APIs of the Sun protocol providers
by (for example) casting a returned Folder object to a
com.sun.mail.imap.IMAPFolder object.  Similarly for
Store and Message objects returned from the
standard JavaMail APIs.
The Sun protocol providers also support properties that are specific to
those providers.  The package documentation for the
IMAP
,
POP3
,
and
SMTP
packages provide details.
