Spammers abuse automatic vacation reply, feature temporarily off

There’s been a lot of posts about the work being done on spam prevention lately on Inside Windows Live, and now the Hotmail Team found that spammers are abusing Hotmail’s automatic vacation reply feature. To prevent spam they’ve decided to temporarily shut off that feature. It’s not going for good, only until the team worked out the best way to prevent it being misused.
