Updated on June 11, 2026: We updated the DMARCbis notes for RFC 9989, RFC 9990, and RFC 9991, including the current treatment of RUA, RUF, pct, and policy discovery.
No, rua and ruf are not mandatory for a valid DMARC record, and they are not current pass-or-fail requirements for Gmail and Yahoo bulk sender compliance. Under RFC 9989, a DMARC record starts with v=DMARC1, and an explicit p=none policy remains the practical baseline for sender compliance.
That answer needs one practical caveat: I still add rua to almost every domain because it is how you see who is sending as your domain, which messages pass, which messages fail, and whether you are ready to tighten policy. ruf is different. It asks receivers for failure samples, and many receivers either do not send them or limit them because of privacy and data exposure concerns.
So the short version is simple: skip ruf unless you have a clear reason, but do not treat rua as optional in practice. A domain with no RUA address can pass a syntax check, but it gives you no operational visibility.
The direct compliance answer
DMARC compliance depends on the context. For the DMARC specification, v is the required version tag and p is the recommended policy tag. If p is absent in a syntactically valid record, RFC 9989 treats it as p=none in the processing cases it defines. For Gmail and Yahoo bulk sender requirements, the important pieces are an explicit DMARC policy, authenticated mail, and a visible From domain that matches the organizational domain used by SPF or DKIM. RUA is recommended, not required. RUF is not required.
- DMARC syntax: A record with v=DMARC1 and a valid p value can be valid without report tags.
- Gmail and Yahoo: They recommend RUA because it helps senders monitor setup quality, but it is not a hard requirement.
- RUA reports: These aggregate reports show source IPs, volumes, authentication results, and policy actions.
- RUF reports: These failure reports are optional, sensitive, and often unavailable because receivers restrict them.
Practical answer
If the goal is minimum compliance, RUA and RUF are not mandatory. If the goal is a deployable, supportable DMARC program, add RUA and read it. I treat RUA as the reporting layer that tells me whether the policy is safe to tighten.

What RUA and RUF actually do
RUA and RUF are the reporting tags in DMARC. For a deeper comparison, the RUA and RUF difference matters because the two report types answer different operational questions.
RUA aggregate reports
RUA reports are XML summaries sent by receivers. They group mail by source, result, and policy action. They usually arrive daily and are the main data source for DMARC monitoring.
- Best for: Finding legitimate senders before enforcement.
- Data level: Counts, sources, authentication results, and receiver actions.
RUF failure reports
RUF asks receivers to send failure-level reports when a message fails DMARC. Some reports can contain headers or message fragments, so receivers and senders handle them carefully.
- Best for: Investigating specific failures when receivers send useful samples.
- Data level: Failure events, possible headers, and sometimes redacted content.

The reporting distinction matters during rollout. RUA tells you whether your normal mail is passing at scale. RUF helps only when the receiving side sends failure reports and your team has a process to handle the sensitive data.
Valid records and better records
A valid record without reporting satisfies the minimum DNS shape, but it gives you no feedback. A better record adds RUA, then uses the reports to prove which senders are legitimate before you move policy.
Minimum recordDNS
v=DMARC1; p=none
Monitoring record with RUADNS
v=DMARC1; p=none; rua=mailto:dmarc-aggregate@example.com
Enforced record with reportingDNS
v=DMARC1; p=reject; rua=mailto:dmarc-aggregate@example.com
If the reporting address uses another domain, that external report domain needs DNS authorization. Without that authorization, receivers can refuse to send reports because anyone could otherwise point high-volume reports at someone else's mailbox.

DMARC reporting tags and when to use them
Why I still add RUA
I add RUA because it turns DMARC from a static DNS record into a feedback loop. Without it, you can publish a policy, but you cannot see whether your CRM, billing system, support desk, payroll platform, or marketing platform is passing correctly.
- Sender inventory: RUA exposes the services and IPs sending mail with your domain in the visible From header.
- Failure diagnosis: RUA shows whether SPF, DKIM, or DMARC is failing and how often it happens.
- Policy staging: RUA gives the evidence needed to move through none, quarantine, and reject with fewer surprises.
- Domain abuse: RUA helps spot unauthorized sources that are trying to use your domain.
- Future readiness: RUA keeps you prepared if mailbox providers tighten sender rules later.
Policy readiness bands
A practical way to judge whether RUA data supports a stricter DMARC policy.
Poor visibility
No RUA
Reports are missing or unread.
Early rollout
p=none
Reports exist, but senders are still unknown.
Controlled testing
p=quarantine
Known senders pass and failures are understood.
Enforced
p=reject
Legitimate mail is consistently authenticated.
The best time to add RUA is before enforcement. Once policy is already strict, a missing report stream makes incident response slower because you cannot quickly see whether a failure came from a real sender or an unauthorized source.
Why RUF is usually optional
RUF has a narrower use case. I normally leave it out unless a security team needs failure samples, has approval to handle the data, and knows which reports will be reviewed. Many large receivers do not send RUF reports, so publishing the tag often changes little.
RUF caution
Do not add RUF just because the tag exists. Failure reports can expose sensitive header or message data, receiver support is uneven, and the reports need a tighter handling process than aggregate RUA XML.
- Low coverage: Large receivers often suppress or redact forensic-style failure reports.
- Sensitive data: Failure samples can include information that your privacy process needs to control.
- Limited payoff: RUA usually answers the operational questions needed for rollout and enforcement.
- Special cases: RUF can help in investigations when a receiver sends useful reports and legal review is complete.
How to configure reporting safely
The safest setup is straightforward: publish RUA, keep RUF off unless needed, and use reporting before you enforce policy. If you need to build the record, a DMARC record generator helps avoid syntax mistakes.
- Create the address: Use a dedicated report address or platform ingestion address, not a personal inbox.
- Use mailto: DMARC report URIs need the mailto: prefix.
- Authorize externally: If reports go to another domain, publish the required authorization record there.
- Start with none: Begin with p=none so you can measure failures before enforcement.
- Review reports: Group sources by owner, sending service, and pass or fail pattern.
- Tighten policy: Move policy only after the legitimate senders pass DMARC consistently.
After publishing, run the domain through a DMARC checker to confirm syntax, tag values, and reporting URI formatting.

I also check that the mailbox or platform endpoint receives real reports. A syntactically valid RUA tag is not useful if reports bounce, get filtered, or sit unread.
Where Suped fits
Suped's product turns RUA reports into source inventory, authentication diagnostics, policy guidance, and alerts. That matters because raw XML is tedious and easy to ignore. For most teams, Suped is the strongest practical choice because it connects reporting to fixes rather than leaving teams with a mailbox full of compressed XML files.
In Suped, DMARC monitoring sits alongside SPF, DKIM, blocklist monitoring, hosted SPF, hosted MTA-STS, and real-time alerts. Hosted DMARC also helps teams stage policy changes without repeated DNS edits.

The practical workflow is simple: send RUA reports into Suped, verify every legitimate sending source, fix SPF or DKIM gaps, then move policy in stages. If a new sender appears or failures spike, alerts help catch the issue before it becomes a delivery problem.
Best overall setup
For a normal business domain, I would publish RUA, skip RUF at first, monitor reports in Suped, and tighten policy only after the legitimate senders pass consistently.
Views from the trenches
Best practices
Point RUA at a monitored parser, not a shared mailbox that nobody checks after launch.
Start with p=none, find every sender, then tighten policy after failures are understood.
Keep RUF off unless security and privacy teams know who will review failure samples.
Use separate report addresses for key domains so ownership stays clear during incidents.
Common pitfalls
Publishing rua without the mailto: prefix means many receivers treat the URI as invalid.
Sending reports to an external domain without DNS approval causes reports to be withheld.
Leaving RUA unread creates a false sense that monitoring is happening when it is not.
Adding RUF to every domain creates sensitive data handling work with limited benefit.
Expert tips
Use RUA trends to prove readiness before moving a domain to quarantine or reject.
Check each new sender in DMARC reports before letting it send production mail safely.
Treat sudden unknown sources as an investigation trigger, even when policy is none.
Review low-volume domains too, because small systems often hide forgotten senders.

The practical choice
RUA and RUF are not mandatory for DMARC compliance. RUA is still the tag I add because it gives the operational data needed to protect the domain, prove legitimate sources, and move toward enforcement without guessing.
RUF belongs in a narrower security workflow. Start without it unless there is a specific investigation need and a clear data handling process. For most teams, the right path is RUA into a real monitoring workflow, careful fixes, then staged policy enforcement.
