26. Email

26.1 Introduction

The Spring Framework provides a helpful utility library for sending email that shields the user from the specifics of the underlying mailing system and is responsible for low level resource handling on behalf of the client.

The org.springframework.mail package is the root level package for the Spring Framework's email support. The central interface for sending emails is the MailSender interface; a simple value object encapsulating the properties of a simple mail such as from and to (plus many others) is the SimpleMailMessage class. This package also contains a hierarchy of checked exceptions which provide a higher level of abstraction over the lower level mail system exceptions with the root exception being MailException. Please refer to the Javadocs for more information on the rich mail exception hierarchy.

The org.springframework.mail.javamail.JavaMailSender interface adds specialized JavaMail features such as MIME message support to the MailSender interface (from which it inherits). JavaMailSender also provides a callback interface for preparation of JavaMail MIME messages, called org.springframework.mail.javamail.MimeMessagePreparator
