[exim] Evaluation logic in 'warn' statements?

Hi list,

Given this statement in acl_check_rcpt:

    warn
        add_header = X-SomeHeader: somevalue
        recipients = somerecip@???
        control = dkim_disable_verify

I find that the header is added to -all- messages while i'd expect
the 'recipients'-condition to prevent that. When the add_header and
recipients line are swapped it does works as i'd expect.

Is that behaviour ... expected? ;)
Exim 4.92, this is.

Thx,
-Sndr.
