Adobe announced that hackers had broken into its systems, stealing some of its source code and stealing information on 2.9 million customers. The company said that it was contacting customers via email to tell them how they can change their passwords. But Gmail has mistakenly blocked Adobes warning as spam.

Unless you trust the sender, dont click on links or reply with personal information.”]
