You can test header lines added at MAIL or RCPT time in the DATA ACL.
The reason for not seeing them earlier is that the header data structure
does not yet exist because the message has not yet been received.
This is documented.
There is a Wish List item to change this, but I don't know if/when it
will be done.
As you have found, you can make use of the $acl_ variables to do some of
what you want.
