Hi Sharyn-   It has to do with double negatives.   Let's simplify it a bit to two domains, A and B.   The or logic would work if you wanted to delete messages from your domains (if from contains A or from contains B). But since you want to take action only if it does not contain contain these items, you have to be more circumspect about the rule.    No matter what the sending domain is, it cannot be both A and B. The rule as you wrote it states "If it does not contain A or does not contain B, delete the message." A message from A will fail the first clause but pass the second clause. Since it is OR'd, the message need pass only one clause to pass the test and be deleted. In fact, all messages will satisfy the rule, and all will be deleted - the effect you saw.   So you make the rule "If it does not contain A and does not contain B, delete the message." That way if it is either A or B it will fail one clause or the other. Since the clauses are AND'd, the message will fail the rule and it will not be deleted. Everything else, which comes from neither A nor B will pass both clauses and therefore pass the test, and will be deleted.   I some ways, its sort of like trying to suss out your incomes taxes... "If you did not answer "yes" to item 38 on page 13b, enter 462.50 on page 12 line 19 and do not skip the next three pages..."   :-)   -d     ----- Original Message ----- From: Sharyn Schmidt To: Imail_Forum@list.ipswitch.com Sent: Thursday, March 30, 2006 10:21 AM Subject: RE: [IMail Forum] Rules help   Try using AND instead of OR...    Thanks, Dave.   Using AND worked, although I guess I don't understand the reasoning behind it.   Appreciate the help!!! :)   Sharyn
