This is the default in Debian's exim4:
  # Accept if the address is in a local domain, but only if the recipient can
  # be verified. Otherwise deny. The "endpass" line is the border between
  # passing on to the next ACL statement (if tests above it fail) or denying
  # access (if tests below it fail).
  #
  accept
    domains = +local_domains
    endpass
    message = unknown user
    verify = recipient
