In Confluence 4.x Server we were able to provide our own implementation of notificationsSender to do some custom manipulation of email notifications (adding stuff to email header) for watched spaces. Trying to d the same thing in confluence 6.2 I see the constructor for our implementation is being called but no other methods are called when a page is changed and we do receive the existing email. I have tried both including the implementation in a plugin and in the classes directory and get the same results. What am I missing or do email notifications just work differently in 6.2?
