In order to bring some sanity to my Inbox, I have been generating rules (either from the short [left click] or long [right click] menu). However, I now learn that there is a limit to the number of these the system allows me to create due to the size of the "cache" devoted to this function.

Please send instructions on how I can increase the size of this "cache."

PS: Kindly send easy-to-understand instructions as I am very, very low-tech. (I don't even know what a "cache" is). Thanks
