## Interface MimeMessagePreparator

-     public interface MimeMessagePreparator

  Callback interface for the preparation of JavaMail MIME messages.

  The corresponding `send` methods of `JavaMailSender` will take care of the actual creation of a `MimeMessage` instance, and of proper exception conversion.

  It is often convenient to use a `MimeMessageHelper` for populating the passed-in MimeMessage, in particular when working with attachments or special character encodings. See `MimeMessageHelper's javadoc` for an example.
