[exim] Access $domain in ACL?

I am using acl_smtp_data to execute anti-spam/anti-virus checks.

It works fine.

I'm now trying to use logwrite if the result of the scan indicates the
message contains a virus. That part is also working, when a virus is
detected I can write to the log.

The problem is, I want to include the domain of the recipient in the log
but $domain comes up empty.

I can write the spam score and $sender_address_domain without issue.

What is the requirement for $domain to be populated?
