Hello Charlie!

Thanks. But your suggestions does not work.

I know that it is possible to delete the emails with the help of various clients and infact I checked it by one of the email client on WIN GUI. However, its not possible to be sure the first message is exactly the message that GMail has inserted. Also it would be an extra-ordinary amount of work, lets say about 20 hours, to sort 5000+ messages, one perhaphs may need a week of office time and the charge of an IT Eng. per hour does not bring any return in comparision to the FREE Email services I offer.

Further, this would be a one time work. The problem remains.
