I tried to put this on a general thread, but there isn't one.
I have an email address I use exclusively for Adobe and I have just received an email allegedly from Royal Mail saying a parcel is being held with border protection. It has zip attachments which I haven't opened. I am not expecting a parcel and if I had ordered something I would not have used my exclusively-for-Adobe email address. I'll be deleting this email address and creating another for emails to/from Adobe.
Most of you will be using general addresses and may miss the connection. So be warned, probably a lot of spam will be coming your way because of the security breach at Adobe.
