Hi,
While this is a long long way from a WAMPServer issue, it would have been really quite useful to know what your hosting company suggested AND what you actually did.
I am guessing that the tool for you would be phpMailer, a PHP library that takes most of the pain out of sending email when you dont have your own MailServer. Did you use that or are you just attempting to use the PHP mail() function.
