Automate Mac Mail mailbox rebuilding

[BackInTheSaddle]

I recently restored my entire system from a Time Machine backup. Everything seems to have come back just fine except for my Mail mailboxes. It looks like I need to rebuild each mailbox. I have literally hundreds of mailboxes and I shudder at the prospect of having to select each one individually and rebuild them.

Is there any AppleScript or other program that will do this automatically?

Automating rebuilding mailboxes

On automating rebuilding mailboxes: several posts I have seen suggest removing the Envelope Index from ~/Library/Mail, the idea being that this forces all your mailboxes to be rebuilt at once. I have hundreds to rebuild and wonder if this works. Any info?
