Sending an email with php should be an easy task - if you're a little familar with that language:
http://php.net/manual/en/function.mail.php
Then in C2 you can make an ajax request to the php-file. In the tutorials section is an explanation how to use the ajax-plugin. I suppose a GET-request similar as shown in the tutorial will do a good job for the first tests. <img src="smileys/smiley1.gif" border="0" align="middle">
