[MlMt] Creating rules - cannot get mail sorted to smart mailboxes

[James Coffey]

My old setup had a number of smart mailboxes with rules that sorted the mail - New Messages, specific addresses, etc.

Now, when I try to set a rule to move mail nothing happens.
Mailboxes -> Any - All Messages
Conditions -> Message is not read

I cannot add any rules and when I could it did not allow me to move messages to the samrtmailbox
