I got an email from my client a couple of hours ago to say he had received numerous emails from the site.
It appears that he IS getting the emails from the page.
I just did a test and logged into the customers webmail, and I can confirm what he says, he is getting them with the form in its current state on the site.
I have still however contacted fasthosts as advised to see why the other email addresses, email@example.com , firstname.lastname@example.org, email@example.com, and your webassist email, where not received by us respectfully.
Could it be an issue with cc's not coming through although the main email address is working maybe?
They have opened a ticket and I await their reply.
Once again thanks for your help.
I will keep you updated on this issue.
