That particular setting had no effect at all for me in the case of invalid recipients. The subject of dictionary attacks has been discussed at great length. As Imail is currently deployed you do not have many options: 1) you can set up a nobody alias and the dictionary attacks will diminish or even cease. By the way the largest single session I recorded had more than 2,000 recipients. a) the downside is that spam will increase 2) Roger Heath reported good results with Black Ice Server 3) You can block addresses using the access list but I for one gave this up as a lost cause 4) You can employ an IMGATE solution and kill the attacks at a low rejected recipient rate After considerable effort and programming I chose Number 1.
