Exempting Certain Mailboxes from Filter

I have multiple mailboxes and would like to exempt one particular mailbox from any filtering or processing by SpamSieve. Is there a way to do this? I tried a whitelist rule adding to address contains <name of mailbox> but that does not work. Thanks!

You can create a Whitelist rule for Any Recipient, and that will make SpamSieve treat all messages to that account as good (except for ones where you are blind carbon copied and your address does not appear).

Another option would be to configure your Mail rules to bypass SpamSieve completely for that account, as described in this thread.

Thanks for the info!
