Postfix can speak XFORWARD towards Amavis, and Amavis is able to 
interpret it. According to [1] there is no sasl-related attribute.

I was not aware that Postfix smtp can speak XCLIENT, I only knew about 
smtpd via smtpd_authorized_xclient_hosts. How do you do that exactly? 
Also, I do not see any XCLIENT-related Amavis code.
