I’m one of the unlucky Sonoma users whose SpamSieve mail extension doesn’t work out of the box. Fortunately, it works ok after ticking “filter in other mailboxes.”

SpamSieve 3.0.1b2 can now automatically filter new messages in the inbox that Mail failed to send to the Mail extension. So, in most cases, you no longer need to do anything to work around this Mail bug.
