 *       the mode is changed from online to offline, the current sending

 *       operation is cancelled.

 * COutboxSender

 * Sends sms messages from the outbox when offline is changed back to online.

 * It only tries to send message once. If sending fails due to other reasons

 * than offline mode, then it is up to the user to go to outbox and send it.

 * Note: At the moment only sms'es are sent. MMS messages are sent by mms mtm

 * and emails are saved to outbox as 'During next connection' and those must

 * not be sent.
