cant get smtp email from wordpress

I am on 3.03 and use a templatic theme called kidscart on one website I have and also on 3.03 on another website I have using a different theme. So I dont think that the issue I am having is theme specific, currently the issue is that i cannot receive the reset password request or new account creations emails as well on both websites.

I have tried several smtp plugins with no result, have also tried modifiying the library/functions/general_functions.php
find: wp_mail($toEmail, $subject, $message, $headers);
replace with:
mail($toEmail, $subject, $message, $headers);

Again no change in behavior still cant get any emails related to accounts, forgot passwords or new accounts. Any suggestions??
