From observation to a useful check
- What was observed
- The DNS records and classifications in this snapshot.
- What it means
- MX describes inbound mail; SPF authorizes senders.
- What is unknown
- The actual sending IP, nested SPF dependencies, inbox placement and commercial relationships. MTA-STS, TLS-RPT and BIMI adoption are not measured.
- Next check
- Verify current DNS and test a real message: run an inbox placement test.

Recorded DNS history
Registry presence: first seen 2026-04-28; last seen 2026-09-07. These are appearances in our domain registry, not domain registration dates or earlier DNS values.
This history starts with saved RR captures. Provider market-share charts are aggregate context, not this domain’s DNS history. Dates identify observations; no continuous validity between them is implied. Equivalent RR states are combined, ignoring response TTL and capture-time changes. Up to 30 distinct RR states and 60 dated captures are retained within a per-domain byte limit.

Changes to jinkosolar.com
No entry for this domain appears in the current public change feed. The feed is a selected sample, so this does not establish that its DNS stayed unchanged.
Start monitoring to build a history from your first check, or explore observed changes across the dataset.
SPF diagnostics
Static observations from the published SPF record. No nested include or redirect dependencies were evaluated. The actual sending IP and evaluation path are needed to assess the RFC 7208 limit of 10 DNS-dependent terms.
Modern mail security across the dataset
The required DNS labels are not queried. Adoption is unknown for this domain and for the population. Apex TXT anomalies are listed separately in the security posture report.
Reverse DNS of inbound MX hosts
These are separately dated observations of inbound MX addresses. They do not identify the actual sending IP. To assess outbound mail, check current forward and reverse DNS of the actual sending IP; FCrDNS and delivery were not measured here.
mx4.jinkosolar.com
Definite negative PTR answers were observed for all addresses of this MX.
DNS attempt: 2026-09-08 09:46:06 UTC. 1 of 1 addresses queried; 1 definite address results in the saved observation.
| Observed IP | Observed PTR names | DNS observation |
|---|---|---|
185.232.59.206 | — | Negative PTR answer |
Name relationships are not a forward-confirmed reverse DNS test.
mx3.jinkosolar.com
Definite negative PTR answers were observed for all addresses of this MX.
DNS attempt: 2026-09-08 09:46:06 UTC. 1 of 1 addresses queried; 1 definite address results in the saved observation.
| Observed IP | Observed PTR names | DNS observation |

Name relationships are not a forward-confirmed reverse DNS test.
Where jinkosolar.com stands
The same snapshot cut by zone, by list position and by how alive the published policies are.
- At this list position the top three mailbox providers hold 53.9% of domains (Google Workspace, Microsoft 365, Unknown / Other).
- Across the dataset 25.1% of DMARC records are inert — policy does nothing and no reports are collected.
How to interpret these observations
MX identifies the observed inbound mailbox or gateway. SPF includes identify services authorised to send for the domain. DMARC shows the published authentication policy. The dataset currently contains 2 populated signal groups for this page.
Observed deliverability context: based on the available observations, this page describes DNS configuration only. It does not represent a complete audit of jinkosolar.com and does not prove that a particular message reaches the inbox or spam folder.
