In the documentation 40.23 ACL conditions you have:
recipients = <address list>
This condition is relevant only after a RCPT command. It checks
the entire recipient address
against a list of recipients.
The important part of it is probably the "entire" address part of it. I
guess that this address is expanded with your default domain and looks
something like mytestid@???.
Another way is to use local_parts as condition, but I'd think that, if
you have more than one domain as local domain in your setup, you should
check the domain part of the address as well.
You can always debug your ACLs by running exim -bh <remote ip address>
where this address is the address exim takes as the host the test SMTP
session is supposed to come from. You then can simulate an entire SMTP
session and get the output of what exim does with what data and which ACL.
