Managing Mail Rules

I got a lot of emails from a few sources. Then that thread will shutdown and I won’t get any more. But the source of the emails will always be around.

I found a great tool for managing Sametime contacts who are not valid. Is there any kind of tool for Notes clients that will make managing and manipulating mail rules easier? I have tried to use the OR statement in a rule but I can only add a few threads before the rule ceases to function.

Any ideas or suggestions would be appreciated.

TIA
