* @short Resource implementing mail transport capability.

* This class allows a resource to provide mail transport (i.e. sending
* mail). A resource than can provide mail transport inherits from both
* ResourceBase and TransportResourceBase, implements the virtual method
* sendItem(), and calls itemSent() when finished sending.
*
* The resource must also have the "MailTransport" capability flag. For example
* the desktop file may contain:
\code
X-Akonadi-Capabilities=Resource,MailTransport
\endcode
*
* For an example of a transport-enabled resource, see
* kdepim/runtime/resources/mailtransport_dummy
