Good news for Mail Act-on users who are not prepared to try to install the plugin manually under Leopard.
Scott has created a Leopard-friendly installer 
that will put the bundle in your Mail directory and run the Terminal commands needed to re-enable bundles in Leopard (see an earlier post for the text of the commands).
He hasn’t updated any of the code yet, and there is one small bug — using Mail Act-on to move a message with a Leopard Mail to-do attached to a different folder may break the link to the message in the to-do.
This is a small price to pay for the plugin that does all the heavy lifting for me, giving me a quick and smart filing workflow.
I don’t know how anyone could use Mail.app without it. Neither do Merlin Mann and Amit Gupta.

Finally!!!
I agree – last week w/o Act-on made a real mess in my Inobx.. not to mention slow-motion while working. Getting back to inbox zero again ;)
Hallelujah! Maybe Leopard was the best thing that could have happened for Morrison. Certainly losing Act-On functionality brought home to me just how essential this plug-in is, which prompted me to drop some paypal goodness in his mail box. Perhaps others will follow suit.
It’s a great information. Thanks!
I’m going to install Leopard today evening and was wandering, what will I do without the best mail plug-in :)
