This is a built-in functionality in Exim, do similar to this:

acl_smtp_rcpt = check_rcpt

begin acl

check_rcpt:

     accept
       verify = recipient/callout
       domain = example.com


     deny
       message = Recipient address unknown


You need to read about "Address Verification" in the documentation:
