There's a lot of email viruses being spread around the internet right now. Check out this thread on the Digital Home Canada forums. I just got an email, supposedly from staff at Rogers, telling me my email account would be terminated if I didn't respond by opening the attachment. Thing is, it was my Blackberry account, and I can't open attachments with my BB 950! Dumbasses. The sender address spoofing can be really tricky, some emails appear to be email sent from my account being bounced, when in fact they aren't at all. I just used this and this, everything came out clean.
