@noaneo: That works UNTIL you have the contact form on a subdomain. The mail address ([email protected]) is connected to the main, not sub domain and thus won’t be validated by contact form 7! If I enter a fictive subdomain E-Mail like [email protected] THIS E-Mail address is validated by contact form 7 (stranely enough) in the backend, but of course the contact form won’t send any mail as this mail doesn’t exist and even can’t be created on my provider’s backend. So.. With all my main domains the new form works, but not with my sub domain!
