I am using Mail 3.5 on a iMac 2.8GHz, with OS 10.5.6. I have about 400 rules for deleting SPAM. Has anyone figured out a way to sort the rules numerically, and why do the rules some times want to pick a rule number like 3 over and over again, when it's already reserved? I thank you for your advice and will go back to lurking. Cheers. Murray snowbound in Medicine Hat, AB
