An example might look like:
-event_action = ${if = {msg:delivery}{$event_name} \
+event_action = ${if eq {msg:delivery}{$event_name} \
{${lookup pgsql {SELECT * FROM record_Delivery( \
'${quote_pgsql:$sender_address_domain}',\
'${quote_pgsql:${lc:$sender_address_local_part}}', \
The equivalent check on the server for client certificates is not
implemented. At least one major email provider is using a client
certificate which fails this check. They do not retry either without
-hte client certificate or in clear.
+the client certificate or in clear.
It is possible to duplicate the effect of this checking by
creative use of Events.
A TLSA lookup will be done if either of the above options match
and the host-lookup succeded using dnssec.
-If the TLSA lookup succeeds, a TLS connection will be required
-for the host.
+If a TLSA lookup is done and succeeds, a DANE-verified TLS connection
+will be required for the host.
(TODO: specify when fallback happens vs. when the host is not used)
-If dane is in use the following transport options are ignored:
+If DANE is requested and useable (see above) the following transport
+options are ignored:
hosts_require_tls
tls_verify_hosts
tls_try_verify_hosts
tls_crl
tls_verify_cert_hostnames
+If DANE is not usable, whether requested or not, and CA-anchored
+verification evaluation is wanted, the above variables should be set

Currently dnssec_request_domains must be active (need to think about that)
and dnssec_require_domains is ignored.
