Add received spam senders to blacklist with one click
When I get a spam email I would like to be able to blacklist the sender with one-click ( maybe 2 clicks or a right-click) to add them to my blacklist without having to copy and paste or re-type the spammers email address, please.

And I would add to that the option to permanently delete the email at the same time. At the moment the process is to block them, then delete them to Spam, then go into Spam and permanently delete. I do the same thing every time I receive suspicious emails, usually with attachments that I don't ever want to open. So make it an all in one process.

blacklist should answer with "550 recipient unknown / no such user here". ps i think a whiteliste would work better for me.
