I really agree to that. A feature in webmail to either "Add sender to blacklist" or "Add domain to blacklist" would be a real life saver.
I can mark emails as spam and that will increase the likelihood of spam detection next time, but that obviously is not as definite as putting a sender on a blacklist.
