Could perhaps be, that Amavis is not storing the XCLIENT variable
LOGIN (http://www.postfix.org/XCLIENT_README.html
<http://www.postfix.org/XCLIENT_README.html>) in mail_via_smtp() where
should handle LOGIN XCLIENT attribute?.
Postfix can speak XFORWARD towards Amavis, and Amavis is able to
interpret it. According to [1] there is no sasl-related attribute.
I'm sending mail traffic to Amavis, using XCLIENT extension
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.
