Thanks Alieu. l have been looking into that.

 Jabou and others,

 The only possible and perhaps most effective way of avoiding unwanted mails
 is by blocking the sender's address.You just have to make some
 configurations and the rest is easy.Any mail that originates from this
 blocked address is automatically rejected and returned to the sender.

 Please try to do that,it's quite annoying to get mails that you don't
 desire.
