There is no such thing. I wonder why folk would know that we usually add the sender to the blocked senders and not to look for a delete and block button?
When I go to Safty Options and click on Blocked Senders, it says at the bottom "When I click Delete and Block". Under that it says "Bounce the blocked messages back to sender". I have the box next to it checked. Nowhere on my e-mail do I find where I can click on Delete and Block. I'm wanting to know where this feature is located. I am using the latest version of Windows Live Mail 2011 and my operating system is Windows Vista which I keep updated.
