Script to run Apple Inbox Rules

**Note:** I am *not* asking how to create a rule which runs an Applescript. I want to go the other way around: run a script that will apply existing rules to all the messages in the inbox. That is, simulate 1. Select Inbox 2. Select All messages 3. Menu Message/Apply Inbox Rules I have ActOn rules that purge certain old messages, and I'd like a script I can set to run, say, nightly. **EDIT:** My Google search turns up only people doing this by hand or with Keyboard Maestro . Rather discourgingly, I don't see any verb exposed in the Apple Mail script dictionary to run the rules, only to make or edit them. (See screenshots.) Is this really so difficult?
