You may elect to do one of three items after reporting a message as either spam or innocent.
First, you can decide to do nothing - the message will be reported as either spam or innocent but will otherwise remain unchanged in your mailbox.
Second, if reporting a message as spam, you can instead have the message be immediately deleted. This setting has no effect on reporting a message as innocent.
Third, after reporting a message as spam the message will be deleted from the current mailbox and moved to your spam folder. Alternatively, if reporting a message as innocent the message will be deleted from the current mailbox and moved to your INBOX.
