It seems that sending mail through a smart host may be unreliable at this point. I have two boxes running 6.819 using a primary filtering box (non ASL) as a smart host. They are set to authenticate over TLS to the filtering box, but the connection times out before the messages are sent. If I remove the smart host configuration then the messages eventually filter through the ASG boxes. This works with the current V6 version that was on both machines before moving to the V7 Beta.
