I am able to sync my mail rules between my macs. This is supported through iCloud and Lion, however, my rules are not synced to my iCloud account. For example, if I login to my icloud account via a browser (not using apple mail client) my rules are not imported. This seems silly as it would be easonable to assume I would want the same rules available through the icloud web interface. Even more disturbing is that my email rules no longer work reliably in my apple mail client. I receive messages marked as junk from icloud, but they are not messages I want marked a junk; I create a new rule it doesn't work or works the first time, but no longer. This is becoming frustrating and I am considering returning to gmail as it works more reliably.
