I have had correspondence with Fasthosts regarding the issues we are facing and there latest reply was:
"We are currently checking and will send you update regarding this issue. I'd like to request for the email password in your next reply as we need to check results to our diagnostic test. We will trace and see if this got to do with the current script use by this website.I just like to request if they (Webassist) were able to check the sample mailform in the article we sent you as they can configure the current scripts and if they have tested it in their end.Please let me know how it goes."
Where do we go with this?
