Email Notification Plugin: Notify when post arrives via /xmlrpc.php

Hello,

I just installed the plugin, works fine so far! But, I think the most important function (for me) is not implemented yet: I would like to see the plugin send mails when there is a “external” message posted in the blog, in my case a automatic post from flickr.com, which is send to /xmlrpc.php. When these messages are posted there is not send any mail to my users.
What can I do?
