ASP and form handling problem / query

I am having soom weird problems with my forms, even basic forms, source or by myself, I find that on submit the page does exactly as it is told, and all appears to be sailing. However My email account does not get the email.

I am so puzzled I have hit a dead end on this one. Can this be a problem, and is there a solution. Normal mail comes through fine, but just through the form, and everything looks perfect.

Please if anyone can shed light on a solution or ideas I would be greatful for your help
