Rule to move older emails from Inbox to Archive folder "On My Mac"

I've got an IMAP email account which has limited server space. When I move a message from my Inbox to a folder I've created as an archive mailbox its removed from the server and is now stored "on my Mac". That's good as it means I won't fill up the server and have messages bounce back to their sender.

I'll forget to move messages though so what I need is a Rule to move messages from my Inbox to my Archive folder 60 days after I receive them. I can't work out how (if) I can do that. I'm not sure if the available tools in Rules can do this. I've had a go and can't seem to make it work.

Any ideas?

It needs to be along the lines of:

If any message in Inbox is received more than 60 days ago move message to mailbox Archive.

Thanks!
