Assign long email addresses to spam
Create a yahoo spam filter which sends messages with long from addresses (not displayed name bur the address you see when you hover over the name). EXAMPLE Address: IamAspamSenderThatusersHATE@ zsflxkjvvzlkxcvjlzkxcjv;lzkxcvj;lkjvzxcv;kj.somedomain.
If the user could be able to define what is "long" for them would be a plus. For me 10 sender length and 10 domain length charactors
