I want to filter out some specific (many conditions) messages that are (ultimately) stored in Spam folder in Gmail. However, according to this article I cannot use in:spam, is:spam or label:spam filter conditions because filters containing such condition supposedly never match any incoming messages.
Is there any workaround for this problem?
Is there any other way (using message filters in Gmail) to "intercept" all emails that Gmail thinks are spam (and is going to deliver them to Spam folder) before they're actually sent to Spam folder?
