No.
For *remote* domains, it only checks if there are DNS records. For
addresses handled locally, it verifies that the recipient can be
delivered to. I'm simplifying slightly by implying that this
distinction is by domain; it usually is.
It's worth reading chapter 3 of The Exim Specification (spec.txt with
Exim or online at
www.exim.org).
