MimeMessagePreparator (Spring Framework 4.3.30.RELEASE API)

```
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.
