Spammers do what is necessary and reasonably cost effective to achieve their goals. Just like legit senders as well (well, sometimes better). Why should they sign their emails if it's not required to deliver to an inbox? On the flipside though: Authenticating emails is required. But I am certain they would sign the emails if we made that mandatory.... -- Marcel
