What is the best way to handle spam email that appears to be sent from one of my own email accounts? Do I still Train it as Spam or just delete it? If I train it as spam, does it use the return path or the received from IP address where it classifies it and future emails as spam?
Please see the How do I make SpamSieve catch spams sent from my own address? page. And, yes, you should still train them as spam.
