Summary: The DANE domain count is now 3,733,547 (c.f. 3,720,888 last
month and 2,998,143 this time last year).
The number of domains that return DNSSEC-validated replies in
response to MX queries is 20,675,170 (up from 20,310,165 last
month and 17,263,168 this time last year). Thus DANE TLSA is
deployed on ~18.05% of domains with DNSSEC. For more stats,
see <https://stats.dnssec-tools.org/>.
[ See the Credits[0] list below my signature. ]
As of today, I count ~3.73 million domains with correct SMTP DANE TLSA records
at every primary MX host that accepts connections[1]. As expected, the bulk of
the DANE domains are hosted by the DNS/email hosting providers who've enabled
DANE support for the customer domains they host. The top 20 MX host providers
by domain count are below.

The real numbers are surely larger, because I don't have access to the
full zone data for most ccTLDs, especially .br, .cz, .fr, .eu, .no, .be,
.pl, .de and .uk. Speaking of countries, the IPv4 GeoIP distribution of
DANE-enabled MX hosts shows the below top 20 countries (each unique IP
address is counted, so multi-homed MX hosts are perhaps somewhat
over-represented).

There are 9,144 unique zones (8,914 last month and 7,482 this time last
year) in which the underlying MX hosts are found. This counts each of
the above providers as just one zone, so is a measure of the breadth of
adoption in terms of organizations deploying DANE SMTP.
The number of published MX host TLSA RRsets found is 19,380 (18,619 last
month and 16,403 this time last year). These cover 19,675 distinct MX
hosts (18,915 last month and 16,670 this time last year, some MX hosts
share the same TLSA records through CNAMEs).
The number of DANE domains that at some point were listed in Gmail's
email transparency report is 841 (this is my ad-hoc criterion for a
domain being a large-enough actively used email domain). Of these, 525
are in recent (last 90 days of) reports (see [2] below my signature).
Of the ~3.73 million DANE domains, 13,107 (13,265 last month and 12,621
this time last year) have "partial" TLSA records, that cover only a
subset of the (secondary) MX hosts. While this protects traffic to some
of the MX hosts, such domains are still vulnerable to the usual active
attacks via the remaining MX hosts.
The number of domains with incorrect TLSA records or failure to offer
STARTTLS (even though TLSA records are published) stands today at 1,320
(1,507 last month and 1,225 this time last year). Some of these have
additional MX hosts that don't have broken TLSA records, so mail can
still arrive via the remaining MX hosts. The affected domain counts for
the top 10 problem MX hosts are:
103 mail.blueconsulting.cz
37 mx1.mdbraber.com
33 mx1.synetcon.net
30 mail.behindthemars.de
20 mx1.logging.ch
18 semark.dk
17 mx1.traxion.com
17 mx01.xworks.net
16 mail.odissee.net
15 artemis.strebsjig.net
To avoid email outages, please make sure to monitor the validity of your
own TLSA records, and implement a reliable key rotation procedure. See:

After eliminating parked domains that do not accept email, the number of
"real" email domains with bad DNSSEC support stands at 1,076 (2,068 last
month). The top 10 name server operators with problem domains are:

If anyone has good contacts at some of these providers, please encourage
them to remediate not only the broken domains (I can send them a list),
but also the root cause that makes the breakage possible.
Just two of the domains all whose nameservers have broken denial of existence

[0] Credits: The coverage of DNSSEC domains continues to improve with
ongoing data support from Paul Vixie of Farsight Security. Credits also
due to ICANN for gTLD data via CZDS, and to the TLD registries for .CH,
.COM, .DK, .FI, .FR, .INFO, .IS, .LI, .NL, .NU, .ORG and .SE. More data
sources of ccTLD signed delegations welcome.
[1] Some domains deliberately include MX hosts that are always down,
presumably as a hurdle to botnet SMTP code that gives up where real MTAs
might persist. I am not a fan of this type of defence (it can also
impose undue latency on legitimate email). However, provided the dead
hosts still have TLSA records, (which don't need to match anything, just
need to exist and be well-formed) there's no loss of security.
