How does hotmail know to reject an email address I have never typed in before? I type an address into the subject line and it turns pink, saying the address is faulty. I have never typed it in before, it has no connection to my email or list of contacts whatsoever. It appears that hotmail has a database of dead emails and recognises these straight away. Has anyone else found this and does this mean hotmail collects all email addresses sent through its service, files and categorises them?

Normally I would just delete your post. You know this is not a hotmail forum. Right?
