Chris, At risk of using a sledgehammer to kill a fly... have you thought about doing the following? 1) Do a scan for worldnet addresses. Copy this list somewhere (into a text file, etc.) 2) Quiet delete all worldnet addresses. 3) Quiet bulk add all the worldnet addresses but the problem one. Sure, it ain't elegant, but I think it'd work, no? :) Regards, Adam the temporarily sigless
