Trained as good still goes to Spam folder

I have multiple email accounts in Apple Mail. On one particular account, there are many emails flagged as spam that I train as good. However, emails from these senders still goes to the spam folder, despite training as good multiple times.

Any solutions?

Most likely, this is not because of SpamSieve. Please see this page for how you can tell whether SpamSieve is moving the messages and what you can do to make the messages go to your inbox instead.
