integrating mail auth with php-imap

Here is the beginnings of my attempt to implement mail authencation with bitweaver. this has been tested with 1.3.1 and doesn't work completely. im a little stuck on getting the authentication to actually trigger my function to test the user/pass of the mail server. Would really appreciate any help on this :)
