Spring Integration provides a namespace for mail-related configuration. To use it, configure the following schema locations.

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:mail="http://www.springframework.org/schema/integration/mail"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
            http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
            http://www.springframework.org/schema/integration/mail
            http://www.springframework.org/schema/integration/mail/spring-integration-mail-1.0.xsd">

To configure an outbound Channel Adapter, provide the channel to receive from, and the MailSender:

<mail:outbound-channel-adapter channel="outboundMail"
                              mail-sender="mailSender"/>

Alternatively, provide the host, username, and password:

<mail:outbound-channel-adapter channel="outboundMail"
                              host="somehost" username="someuser" password="somepassword"/>

	Note
	Keep in mind, as with any outbound Channel Adapter, if the referenced channel is a PollableChannel, a <poller> sub-element should be provided with either an interval-trigger or cron-trigger.

When using the namespace support, a header-enricher Message Transformer is also available. This simplifies the application of the headers mentioned above to any Message prior to sending to the Mail-sending Channel Adapter. Also, note that a boolean value c

<mail:header-enricher subject="Example Mail"
                     to="[email protected]"
                     cc="[email protected]"
                     bcc="[email protected]"
                     from="[email protected]"
                     reply-to="[email protected]"
                     overwrite="false"/>
