Quote from /etc/exim4/conf.d/acl/30_exim4-config_check_rcpt or
/etc/exim4/exim4.conf.template respectively:
# Deny unless the sender address can be verified.

# This is disabled by default so that DNSless systems don't break. If

# deny message = Sender verification failed
# !acl = acl_whitelist_local_deny
# !verify = sender
