Spring XD - mail sink configuration for outlook - outlook

Question

I'm trying to configure Spring XD's mail sink to send messages to an outlook account. This is my stream definition:
stream create outlookMailSink --definition "http | mail --to='\"email#address.com\"' --host=outlook.office365.com --subject=payload+' world'" --deploy
I'm testing using this shell command:
http post --data Hello
I am getting the following error message:
Failed message 1: com.sun.mail.smtp.SMTPSendFailedException: 530 5.7.57 SMTP; Client was not authenticated to send anonymous mail during MAIL FROM
at org.springframework.integration.handler.AbstractMessageHandler.handleMessage(AbstractMessageHandler.java:84)
I have investigated this in the Spring XD documentation and internet searches but I haven't found a solution that works. Can anyone help me with this please?

Answer 1

I found a solution which involves creating a new mail sink module which is a slight modification of spring XD's supplied mail sink module. The stream must also include to, from, host, port, username and password options.
Copy the ..\spring-xd-<version>\xd\modules\sink\mail folder and rename to secure-mail.
In ..\spring-xd-<version>\xd\modules\sink\secure-mail rename both mail.properties and mail.xml to secure-mail.properties and secure-mail.xml respectively.
Replace the contents of secure-mail.xml with the following:
<?xml version="1.0" encoding="UTF-8"?>

<util:properties id="javaMailProperties">
<beans:prop key="mail.smtp.starttls.enable">true</beans:prop>
</util:properties>
</beans:beans>
Create the stream as follows:
stream create outlookMailSink --definition "http | secure-mail --to='\"email#address.com\"' --from='\"email#address.com\"' --host=outlook.office365.com --port=587 --username=email#address.com --password=password --subject=payload+' world'" --deploy
Test using shell command: http post --data Hello
The contents of secure-mail.xml is almost identical to mail.xml, the key is to set the property mail.smtp.starttls.enable to be true in order to enable TLS encryption for communication over port 587. OF course you could just modify Spring XD's mail sink module directly and use this - it's up to you.
I'd be interested to hear if anyone has a better solution to this? For example, is it possible to set the mail.smtp.starttls.enable property on start-up of Spring XD thereby allowing you to use the original mail sink module? I tried this by modifying the xd-singlenode startup script - the property was set but it didn't affect the mail sink module.
