Good morning,
Thanks for the further information.
I have decided that I will treat googlemail.co.uk like any other non existing mail address rather than do special case processing for it.
It's just that having google in it got me wondering especially as far as I can see it did appear to valid once and losing customers because of something so trivial as an email address is never a good idea.
Bye
Ian
