I take it your current e-mail address is with Wanadoo. If so have you tried this click here Several companies use this type of Junk Folder and the BT Yahoo one seems to work well.
The problem with changing your e-mail address is informing everyone that you have done so and you will still need to check it for legitimate mail for months to come.
Unfortunately for me my ISP (Breathemail) doesn`t have such a facility at the moment so I have used Mailwasher click here a free version. (At the moment) This programme, rather like web mail, interrogates and allows you to preview your mail on your ISP`s server before you download it to OE. You can delete the obvious spam, blacklist the sources and bounce (not recommended because it may confrm an e-mail address as valid) with the click of a mouse.
