wordpress emails not working with google apps

When wordpress sends an email to a user registered with an email@somegoogleappsdomain the email never arrives.

I have done a bit of research and it appears this is because data isn’t being passed on to Google Apps account email because WordPress doesn’t use SMTP mail like Google. Rather, the wp_mail() function makes use of the standard PHP mail() function which is trying to send to the address located on our server. There appear to be several plugins out there to help with this but none tested on the latest version of wordpress.

Just wondered if anyone at WPMU DEV had an clever ideas as to how I might solve this issue.

Many thanks
