The very same thing happened to me two weeks ago. And I freaked! My son and my wonderful computer person told me not to worry, it was just my email that was hacked...not my internet. He also said it was most probably a hack into the server's records and that they should be addressing it. They have. I had to change my password with the server (yes, I did verify) and now I feel quite secure....
Hope you are OK now too. It is an old scam and none of my email friends were taken in, but it only takes one for some jerk to make a killing.
Thanks for sharing your experience. These days, we can't be too careful....:)
