A late thought came to me as I checked for spams this morning before using Outlook Express.
The are several sites such as:
mail2web
where you can see your emails as web-mail before they get anywhere near your computer.
It is my habit, particularly on week-end mornings to go there first to delete the junk before downloading.
Bit like Hotmail but you use your normal e-mail addresses and you have to know the name(s) of your server(s).
