Greetings,
DANE and MTA-STS both ensure that email is exchanged encrypted.
Together with researchers from Virginia Tech and Max-Planck-Institut für Informatik, we would like to understand the general trends, operational practices, and challenges of MTA-STS protocol from the mail operators' point of view.
It takes around 5-6 minutes and you can stop participating in the study at any time; we would truly appreciate your participation.
We do not collect any personal information and all answers except the first couple of consent questions are optional. If you do not want to answer any questions, please just leave the field blank.
https://www.surveymonkey.com/r/JKWNDSN
Please do not hesitate to email me if you have questions or comments. Also, please excuse us if you have received this email from different mailing lists.
Thank you very much.

Summary: The DANE domain count is now 4,158,589 (4,069,697 last month).
The number of domains that return DNSSEC-validated replies in
response to MX queries is 23,220,430 (23,199,861 last month).
Thus DANE TLSA is deployed on ~17.90% of domains with DNSSEC.
For more stats, see <https://stats.dnssec-tools.org/>.
A major fraction of the increase in DANE domains is
thanks to Cloudflare publishing TLSA records for the MX
hosts handling inbound email for ~70k customer domains.
[ The credits[0] list is below my signature. ]
Reminder: If you're relying on trust-anchor (usage DANE-TA(2)) TLSA records
matching a Let's Encrypt issuing CA, please note important recent
and upcoming changes in Let's Encrypt certificate issuance:
https://list.sys4.de/hyperkitty/list/dane-users@list.sys4.de/message/HESAY6…
https://list.sys4.de/hyperkitty/list/dane-users@list.sys4.de/message/GLRVY2…
https://list.sys4.de/hyperkitty/list/dane-users@list.sys4.de/message/X4SS2E…
[ There's a still stready trickle of domains whose DANE
authentication fails because the DST X3 cross certificate
for the ISRG X1 root is no longer by default included in
Let's Encrypt certificate chains. ]
As of today, I count ~4.16 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, .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 10,936 unique zones (10,895 last month) 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 22,121 (21,863 last
month). These cover 22,427 distinct MX hosts (22,163 last month, 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 1,381 (1,272 last month, this is my ad-hoc
criterion for a domain being a large-enough actively used email domain).
Of these, 758 (743 last month) are in recent (last 90 days of) reports
(see [2] below my signature).
Of the ~4.16 million DANE domains, 14,232 (14,334 last month) 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 2,669
(2,344 last month). 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:
545 mx2.xcellerate.nl
169 mx2.tkservers.com
72 mail.fiyge.com
66 beta.itcomputers.eu
38 master.redinta.com
24 mx-5.magellanic.eu
22 semark.dk
22 hello.mailray.dk
16 mail.nationaalarchief.nl
14 mx.jmt.gr
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 624 (697 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 one of the domains whose nameservers have broken denial of
existence appears in the last 120 days of Google transparency reports:
mailazy.net

[0] Credits:
Hosting for the DANE/DNSSEC project is donated by isi.edu (Wes Hardaker and
team). Wes also hosts and maintains the https://stats.dnssec-tools.org
website. Thanks go to ICANN for sponsoring acquisition of the server hardware.
Coverage of DNSSEC domains continues to improve with ongoing data
support from Chris Mikkelson from domaintools.com. Credits also due to
ICANN providing gTLD data via CZDS, and to the ccTLD registries for .CH,
.DK, .FI, .FR, .IS, .LI, .NL, .NU 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.

Summary: The DANE domain count is now 4,069,697 (4,022,036 last month).
The number of domains that return DNSSEC-validated replies in
response to MX queries is 23,199,861 (23,122,328 last month).
Thus DANE TLSA is deployed on ~17.54% of domains with DNSSEC.
For more stats, see <https://stats.dnssec-tools.org/>.
[ The credits[0] list is below my signature. ]
Reminder: If you're relying on trust-anchor (usage DANE-TA(2)) TLSA records
matching a Let's Encrypt issuing CA, please note important recent
and upcoming changes in Let's Encrypt certificate issuance:

[ This month there's a stready trickle of domains whose DANE authentication
fails because the DST cross certificate for the ISRG X1 root is no longer
included in Let's Encrypt certificate chains. ]
As of today, I count ~4.07 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, .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 10,895 unique zones (10,719 last month) 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 21,863 (24,636 last
month). These cover 22,163 distinct MX hosts (24,945 last month, 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 1,272 (1,199 last month, this is my ad-hoc
criterion for a domain being a large-enough actively used email domain).
Of these, 743 (683 last month) are in recent (last 90 days of) reports
(see [2] below my signature).
Of the ~4.07 million DANE domains, 14,334 (14,204 last month) 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 2,344
(2,424 last month). 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:
547 mx2.xcellerate.nl
171 mx2.tkservers.com
25 mail.orionpanel.nl
23 semark.dk

15 mail.nationaalarchief.nl

14 mail.liebner-server.de
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 697 (838 last
month). The top 10 name server operators with problem domains are:

them to remediate not only the broken domains (I can send them a list),
but also the root cause that makes the breakage possible.

existence appears in the last 120 days of Google transparency reports:

Hosting for the DANE/DNSSEC project is donated by isi.edu (Wes Hardaker and

Coverage of DNSSEC domains continues to improve with ongoing data
support from Chris Mikkelson from domaintools.com. Credits also due to
ICANN providing gTLD data via CZDS, and to the ccTLD registries for .CH,
.DK, .FI, .FR, .IS, .LI, .NL, .NU 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.

DANE: ATTENTION: Let's Encrypt drops DST X3 from default chain, breaking "depth 2" ISRG "2 1 1" TLSA records...
by Viktor Dukhovni 13 Feb '24
by Viktor Dukhovni 13 Feb '24
13 Feb '24
As of roughly the start of this month, the DANE survey at
<https://stats.dnssec-tools.org> is seeing a steady stream
of validation failures for MX hosts that rely only on:
_25._tcp.mail.domain.example. IN TLSA 2 1 1 0b9fa5a59eed715c26c1020c711b4f6ec42d58b0015e14337a39dad301c5afc3
[ Some also list a no-longer valid "3 1 1" record that broke
when the unerlying EE key was rotated, because they failed to ensure
that certificate renewals do not automatically rotate the key. ]
As promised by Let's Encrypt some months back, Let's Encrypt have
dropped the expired DST X3 cross-certificate from the default generated
"fullchain.pem" file, which now contains just the leaf (EE) certificate
(depth 0) and the intermediate CA (depth 1) issuer (R3, R4, E1 or E2),
the parent ISRG root CA is implicit and there's no longer a legacy
cross certificate from DST for outdated Android devices.
Domains whose MX hosts relied only on the "2 1 1" record for the
ISRG root CA (present in the cross certificate, but absent from
the new chain) are no longer passing DANE TLSA validity checks.
My notices to these domains include the below advice:
[ Perhaps consider: <https://github.com/tlsaware/danebot>?
Your TLSA record designates a root CA key, but, as is common, the root
CA certificate is not included in your certificate chain. It would need

Summary: The DANE domain count is now 4,022,036 (3,988,988 last month)
The number of domains that return DNSSEC-validated replies in
response to MX queries is 23,122,328 (23,098,096 last month).
Thus DANE TLSA is deployed on ~17.39% of domains with DNSSEC.
For more stats, see <https://stats.dnssec-tools.org/>.

Reminder: If you're relying on trust-anchor (usage DANE-TA(2)) TLSA records
matching a Let's Encrypt issuing CA, please note important upcoming
changes in Let's Encrypt certificate issuance:

As of today, I count ~4.02 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, .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 10,719 unique zones (10,449 last month) 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 24,636 (21,169 last
month). These cover 24,945 distinct MX hosts (21,466 last month, 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 1,199 (1,173 last month, this is my ad-hoc
criterion for a domain being a large-enough actively used email domain).
Of these, 683 (674 last month) are in recent (last 90 days of) reports
(see [2] below my signature).
Of the ~4.02 million DANE domains, 14,204 (14,456 last month) 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 2,424
(1,862 last month). 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:
550 mx2.xcellerate.nl
172 mx2.tkservers.com
123 mx2.dotxs.net
106 mx.xobit.nl
35 mx1.mdbraber.com
26 mail.orionpanel.nl
23 semark.dk
22 smtp2.kruik-it.nl
15 mail.nationaalarchief.nl
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 697 (838 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 one of the domains whose nameservers have broken denial of
existence appears in the last 120 days of Google transparency reports:

Hosting for the DANE/DNSSEC project is donated by isi.edu (Wes Hardaker and
team). Wes also hosts and maintains the https://stats.dnssec-tools.org
website. Thanks go to ICANN for sponsoring acquisition of the server hardware.
Coverage of DNSSEC domains continues to improve with ongoing data
support from Chris Mikkelson from domaintools.com. Credits also due to
ICANN providing gTLD data via CZDS, and to the ccTLD registries for .CH,
.DK, .FI, .FR, .IS, .LI, .NL, .NU 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.

Summary: The DANE domain count is now 3,988,988 (3,987,641 last month,
3,733,547 a year ago).
The number of domains that return DNSSEC-validated replies in
response to MX queries is 23,098,096 (23,197,449 last month,
20,675,170 a year ago). Thus DANE TLSA is deployed on ~17.26%
of domains with DNSSEC. For more stats, see
<https://stats.dnssec-tools.org/>.
[ The credits[0] list is below my signature. ]
Reminder: If you're relying on trust-anchor (usage DANE-TA(2)) TLSA records
matching a Let's Encrypt issuing CA, please note important upcoming
changes in Let's Encrypt certificate issuance:

The real numbers are surely larger, because I don't have access to the
full zone data for most ccTLDs, especially .br, .cz, .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 10,449 unique zones (10,192 last month, 9,144 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 21,169 (20,854 last
month, 19,380 last year). These cover 21,466 distinct MX hosts (21,158
last month, 19,380 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 1,173 (841 last year, this is my ad-hoc
criterion for a domain being a large-enough actively used email domain).
Of these, 674 (525 last year) are in recent (last 90 days of) reports
(see [2] below my signature).
Of the ~3.99 million DANE domains, 14,456 (14,431 last month, 13,107
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 1,862
(1,655 last month, 1,320 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:
172 mx2.tkservers.com
48 mail.caop.nl
35 mx1.mdbraber.com
32 mx01.speicher-werk.de
31 mail-03.eu-central-1.aorta.space
26 mail.orionpanel.nl
23 smtp2.kruik-it.nl
23 mail.spreadity.com
22 mail.exot.cz
15 mail.nationaalarchief.nl
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 838 (901 last
month, 1,076 last year). 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 one of the domains whose nameservers have broken denial of
existence appears in the last 120 days of Google transparency reports:

Hosting for the DANE/DNSSEC project is donated by isi.edu (Wes Hardaker and
team). Wes also hosts and maintains the https://stats.dnssec-tools.org

Coverage of DNSSEC domains continues to improve with ongoing data
support from Chris Mikkelson from domaintools.com. Credits also due to
ICANN providing 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.

Summary: The DANE domain count is now 3,987,641 (3,949,527 last month).
The number of domains that return DNSSEC-validated replies in
response to MX queries is 23,197,449 (up slightly from 23,173,417
last month). Thus DANE TLSA is deployed on ~17.18% of domains with
DNSSEC. For more stats, see <https://stats.dnssec-tools.org/>. [
See the Credits[0] list below my signature. ]
Reminder: If you're relying on trust-anchor (usage DANE-TA(2)) TLSA records
matching a Let's Encrypt issuing CA, please note important upcoming
changes in Let's Encrypt certificate issuance:
https://list.sys4.de/hyperkitty/list/dane-users@list.sys4.de/message/HESAY6…
https://list.sys4.de/hyperkitty/list/dane-users@list.sys4.de/message/GLRVY2…
As of today, I count ~3.99 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, .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 10,192 unique zones (9,773 last month) 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 20,854 (20,781 last
month). These cover 21,158 distinct MX hosts (21,077 last month, 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 1,135 (this is my ad-hoc criterion for a
domain being a large-enough actively used email domain). Of these, 614
are in recent (last 90 days of) reports (see [2] below my signature).
Of the ~3.99 million DANE domains, 14,431 (14,236 last month) 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 1,655
(1,873 last month). 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:
172 mx2.tkservers.com

Summary: The DANE domain count is now 3,949,527 (3,923,543 last month).
The number of domains that return DNSSEC-validated replies in
response to MX queries is 23,173,417 (up slightly from 23,180,180
last month). Thus DANE TLSA is deployed on ~17.04% 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 ~3.95 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, .eu, .no, .be, .pl,

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).

Summary: A slow month. The DANE domain count is now 3,923,543
(c.f. 3,924,107 last month).
The number of domains that return DNSSEC-validated replies in
response to MX queries is 23,180,180 (up slightly from 23,141,061
last month). Thus DANE TLSA is deployed on ~16.92% of domains with
DNSSEC. For more stats, see <https://stats.dnssec-tools.org/>.
[ See the Credits[0] list below my signature. ]
A light at the end of the tunnel is that Microsoft are moving
forward with enabling inbound DANE. Though the official
start date is in Q1 2024, the first domain is already live,
with its primary and secondary MX hosts DANE-enabled:
https://twitter.com/VDukhovni/status/1707817430125322421
https://stats.dnssec-tools.org/explore/?digitalcosmos.net
The 3rd and 4th MX hosts aren't yet on the new "mx.microsoft"
platform.
As of today, I count ~3.92 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, .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 9,391 unique zones (9,398 last month) 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 20,808 (20,884 last
month). These cover 21,102 distinct MX hosts (21,182 last month, 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 1,062 (this is my ad-hoc criterion for a
domain being a large-enough actively used email domain). Of these, 548
are in recent (last 90 days of) reports (see [2] below my signature).
Of the ~3.92 million DANE domains, 14,262 (14,274 last month) 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 1,873
(2,180 last month). 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:
178 mx2.tkservers.com
133 mx2.solutive.nl
42 mail.itcomputers.net
37 mx04.speicher-werk.de
35 mx1.mdbraber.com
32 relay.csngroep.nl
24 semark.dk
23 smtp2.kruik-it.nl
20 fsn1-c04.xemo-net.de
19 web1.sys.ccs-baumann.de
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 1,057 (1,357 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 one of the domains whose nameservers have broken denial of
existence appears in the last 120 days of Google transparency reports:

[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.
