No, not really. What the action you describe does is to create a filter
which acts upon information which the undesirable sender provides - his
supposed email address. The worst of the trolls, flamers, OT idiots and
other newsgroup dregs change this information regularly so as not to be
blocked by simple filtering tactics. The information they provide passes no
checks and can be almost anything -- mine says that I am 'no.where@all' but
I can change that in a second or two.
