The use of OCSP-stapling should be considered, allowing

+be limited by the DNS TTL on the TLSA records). However,
+this is likely to only be usable with DANE_TA.
For client-side DANE there are two new smtp transport options,
tls_verify_certificates
tls_crl
tls_verify_cert_hostnames
- hosts_require_ocsp (might rethink those two)
- hosts_request_ocsp
Currently dnssec_request_domains must be active (need to think about that)
and dnssec_require_domains is ignored.
