*** Drupal Hotmail Challenge problem ***

Okay this is a fun one, or who knows could be very very simple for the right person. I have a Fresh Drupal installation, with properly configured DNS, MX records, and SPF records for the domain. When a user registers most all emails from normal email accounts are received perfectly as it is already setup and working fine, The problem is they are not always received through hotmail ( as Drupal has a problem with getting registration emails through to hotmail accounts) it may because the SMTP module that come with Drupal stinks, OR it can be that the way Drupal handles the SPF records on top of an email that hotmail sees it as spam. I have other scripts like Joomla, Xoops etc on the same server and IP that send to all hotmail accounts without a problem but I need this to work with drupal. I can send an email from Drupal from the admin area and it will sometimes show up in hotmail accounts. BUT when a user registers NO emails ever get through. (so it has something to do with the registration module I believe) This is the challenge to get a fresh installation of Drupal to automatically send the password registration emails to any normal hotmail account and working as it should. you can contact me, and I will give you login access so the installation so you can play with it...before you bid too, if you like..its a new install and there is no data that is needed worry about.
