This is weird. I just had a bunch of emails sent from my hotmail account as Spam and were returned as undeliverable. I know that virii can send spam out using your outlook address book, but I don't use outlook. Could there possible be a virus on MSN's internal mail server? I have checked all my machines that I access my account from for keyloggers/spyware/virii - nothing was found. Has this happened to anyone else?
