title: WSO2 Governance is sending email validation e-mails but not for subscriptions
body: <p>Set up WSO2 governance.  Set up axis2.xml so that when setting up an e-mail subscription to a collection it sends a validate e-mail request e-mail fine.  But the subscription is never firing... Tried all events, Create child, update, create LC.</p>
  
  <p>Any help?</p>
  
  <p>Nothing in the log files to say it failed to send.... or that is even tried.</p>
  
  <p>One thing to note is that this subscription is on a custom artifact type's storage collection/</p>
