+If not set, then &%tls_require_ciphers%& will be used.
+Normal SMTP delivery is not able to make strong demands of TLS cipher

+TLS cipherlist configuration stronger will increase security, rather than
+counter-intuitively decreasing it.

.option data_timeout smtp time 5m
This sets a timeout for the transmission of each block in the data portion of
the message. As a result, the overall timeout for a message depends on the size
to this server, its A record, its TLSA record and any associated CNAME records must all be covered by
DNSSEC.
2) add TLSA DNS records. These say what the server certificate for a TLS connection should be.
-3) offer a server certificate, or certificate chain, in TLS connections which is traceable to the one
-defined by (one of?) the TSLA records
+3) offer a server certificate, or certificate chain, in TLS connections which is is anchored by one of the TLSA records.
There are no changes to Exim specific to server-side operation of DANE.
Support for client-side operation of DANE can be included at compile time by defining SUPPORT_DANE=yes
those who use &%hosts_require_ocsp%&, should consider the interaction with DANE in their OCSP settings.
-For client-side DANE there are two new smtp transport options, &%hosts_try_dane%& and &%hosts_require_dane%&.
-The latter variant will result in failure if the target host is not DNSSEC-secured.
+For client-side DANE there are three new smtp transport options, &%hosts_try_dane%&, &%hosts_require_dane%&
+and &%dane_require_tls_ciphers%&.
+The require variant will result in failure if the target host is not DNSSEC-secured.
DANE will only be usable if the target host has DNSSEC-secured MX, A and TLSA records.
will be required for the host. If it does not, the host will not
be used; there is no fallback to non-DANE or non-TLS.
+If DANE is requested and usable, then the TLS cipher list configuration
+prefers to use the option &%dane_require_tls_ciphers%& and falls
+back to &%tls_require_ciphers%& only if that is unset.
+This lets you configure "decent crypto" for DANE and "better than nothing
+crypto" as the default. Note though that while GnuTLS lets the string control
+which versions of TLS/SSL will be negotiated, OpenSSL does not and you're
+limited to ciphersuite constraints.
+
If DANE is requested and useable (see above) the following transport options are ignored:
.code
hosts_require_tls
Do the same for the queue-runner loop, for variables set from spool
message files.
+PP/02 DANE: add dane_require_tls_ciphers SMTP Transport option; if unset,
+ tls_require_ciphers is used as before.

Exim version 4.90
-----------------
2. DANE is now supported under GnuTLS version 3.0.0 or later. Both GnuTLS and
OpenSSL versions are moved to mainline support from Experimental.
+ New SMTP transport option "dane_require_tls_ciphers".
3. Feature macros for the compiled-in set of malware scanner interfaces.
