public abstract class Transport extends Service
Note that Transport extends the Service
class, which provides many common methods for naming transports,
connecting to transports, and listening to connection events.

Message method getAllRecipients),
using message transports appropriate to each address. The
send method calls the saveChanges
method on the message before sending it. If any of the recipient addresses is detected to be invalid by the Transport during message submission, a SendFailedException is thrown. Clients can get more detail about the failure by examining the exception. Whether or not the message is still sent successfully to any valid addresses depends on the Transport implementation. See SendFailedException for more details. Note also that success does not imply that the message was delivered to the ultimate recipient, as failures may occur in later stages of delivery. Once a Transport accepts a message for delivery to a recipient, failures that occur later should be reported to the user via another mechanism, such as returning the undeliverable message.
In typical usage, a SendFailedException reflects an error detected by the server. The details of the SendFailedException will usually contain the error message from the server (such as an SMTP error message). An address may be detected as invalid for a variety of reasons - the address may not exist, the address may have invalid syntax, the address may have exceeded its quota, etc.
Note that send is a static method that creates and
manages its own connection. Any connection associated with any
Transport instance used to invoke this method is ignored and not
used. This method should only be invoked using the form
Transport.send(msg);, and should never be invoked
using an instance variable.

Unlike the static send method, the sendMessage
method does not call the saveChanges method on
the message; the caller should do so.

The provided default implementation queues the event into an internal event queue. An event dispatcher thread dequeues events from the queue and dispatches them to the registered TransportListeners. Note that the event dispatching occurs in a separate thread, thus avoiding potential deadlock problems.
