/**
 * Extended MailSender interface for JavaMail, supporting MIME messages both
 * as direct arguments and through preparation callbacks. Typically used in
 * conjunction with the MimeMessageHelper class for convenient creation of
 * JavaMail MimeMessages, including attachments etc.
 *
 * <p>Clients should talk to the mail sender through this interface if
 * they need mail functionality beyond SimpleMailMessage. The production
 * implementation is JavaMailSenderImpl. Clients will typically receive the
 * mail sender reference through dependency injection.
 *
 * <p>The recommended way of using this interface is the MimeMessagePreparator
 * mechanism, possibly using a MimeMessageHelper for populating the message.
 * See MimeMessageHelper's javadoc for an example.
 *
 * <p>Not as easy to test as a plain MailSender, but still rather easy compared to
 * traditional JavaMail code: Just let <code>createMimeMessage</code> return a plain
 * MimeMessage created with a <code>Session.getInstance(new Properties())</code>
 * call, and check the given messages in your mock implementations of the various
 * send methods.
