I have a student who I was talking with via ICQ. He was telling me that his Yahoo email account was getting filled with lots of emails from a variety of sources (email and ip varies) that are simply blank emails. (nothing in the contents).

Today on Full Disclosure, a member posted an email saying he was getting the same thing but to a regular "non-free" email account. Is anyone else seeing this?

I'm guessing it's one of two things: 1) email list trying to determine if an account is live by getting a response from the receiver 2) worm that has some poor coding and is missing the payload.
