Ignore whispers addons

Hey, im looking for addons that work to ignore annoying players whispering me. Like some kind of addon where i can just set myself to bisy and it will return whispers with a message saying i dont want to be disturbed and i dont have to see their message. Or just simply an addon that only let friends + guildies whisper me and has a whitelist or something like that, ive been trying to look around alot but cant find any that actually works for warmane. I would appreciate any tips as i feel this would help alot with having more peice while playing. If any1 have and uses these kind of addons, please let me know where to find it.
