No, it doesn't. Or at least, it shouldn't.

Well, if Exim were calling the DNS directly itself, it would reflect the
DNS queries and results it is getting, because you have got -d12 set. It
has not done that. This means that the DNS query MUST have been
triggered by the call to gethostbyname(), not by Exim itself.
