wphastings on "Contact Form 7 sending to some email addresses... not Google Apps Mail"

Hi

I have Contact Form 7 set up and working ok except that it will not send to an email address that is hosted on Google Apps for Business.

It does send to other email addresses hosted elsewhere including Hotmail.

I have added an SPF record for my domain but that has not helped.

Is there a way to see where the email submitted by the form is *really* coming from? (ie not the form user's email address but the form's address if that makes sense)

Or is there a way to receive/view errors generated by the form's email not arriving?

Thanks
Pete
