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 rj.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.

5DNS-dependent terms — nested dependencies are not checked; headroom is not confirmed

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.

rj-com.mail.protection.outlook.com

Partial observation: some addresses were not checked or the resolver could not determine their PTR records.

DNS attempt: 2026-09-08 08:16:09 UTC. 3 of 8 addresses queried; 3 definite address results in the saved observation.

Where rj.com stands

The same snapshot cut by zone, by list position and by how alive the published policies are.

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 3 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 rj.com and does not prove that a particular message reaches the inbox or spam folder.

Frequently asked questions

What email provider does rj.com use?

rj.com uses Microsoft 365 for inbound mail (detected from its primary MX record) as of September 7, 2026, per Live Direct Marketing's daily Tranco top-1M scan.

Does rj.com enforce DMARC?

No — rj.com publishes p=none, which only monitors and does not block spoofing (as of September 7, 2026).
