How can we configure JBoss to use Gmail smtp. I am using 4.0.2 and I want Jboss to use gmail smtp. I did something in my mail-service.xml.

<attribute name="Configuration">
 <!-- Test -->
 <configuration>
 <!-- Change to your mail server prototocol -->
 <property name="mail.transport.protocol" value="smtp"/>

 <property name="mail.smtp.starttls.enable" value="true"/>
 <property name="mail.smtp.host" value="smtp.gmail.com"/>
 <property name="mail.smtp.auth" value="true"/>


 <!-- Change to the SMTP gateway server -->
 <!-- Change to the address mail will be from -->
 <property name="mail.from" value="someaddress@gmail.com"/>

 <!-- Enable debugging output from the javamail classes -->
 <property name="mail.debug" value="false"/>
 </configuration>
 </attribute>

But this doesnt work. I keep getting error

"class javax.mail.MessagingException: 530 5.7.0 Must issue a STARTTLS command first 9sm23453515agc"

Can some one help me please?
