Apply rules to messages in mailbox I created some rules in Mail 6.6 application.

Now, I want to apply these rules on my existing mails in mailbox, not just to the inbox, that is going to my mailbox after creation of the rules.

How can I achieve this?
To apply the rules to existing messages, just select the mailbox and use "Apply Rules" from the "Message" menu. Or use the shortcut ⌥+⌘+L
