Introducing The Valimail DMARC Report Analyzer Service

The Email ecosystem is having something of an upgrade next month; the reason for the upgrade is simple and compelling. The fact is that it is too easy to spoof or fake email addresses.

For more information, see the NCSC’s in-depth explanation of the new DMARC rules

All of us have seen emails in our inbox that are trying to induce us into clicking on a link and lots of emails advertising things we aren’t interested in. The unwanted, unsolicited advertising emails are what we refer to as Spam, a subset of carefully targeted and crafted emails that directly target you as an individual. These are the dangerous ones that we refer to as Phishing. When they are successful, sadly, they have often put into train a series of events that can end up with cybercriminals gaining access to your system and, ultimately, your data.

The techniques often employed to trick users by impersonating legitimate, trusted sources of email that often originate from compromised email accounts are called Business Email Compromise. (BEC).

Fake emails put your company at risk. BEC is responsible for 60% of fraud ( because if I can send an email and it looks like it came from an internal email address or someone you trust, you are more likely to act on it.

The changes are focusing on making it more difficult to impersonate valid email addresses

The approach being put into place by Yahoo, Google, and the rest in February employs a system of checks on records that DMARC Domain-based Message Authentication, Reporting and Conformance employ. DMARC is an email authentication protocol. It is designed to give email domain owners the ability to protect their domain from unauthorized use, so the solution lies in the DNS records that every domain ( uses to perform various technical functions.

The need to implement DMARC

Being DMARC compliant involves setting up and monitoring a group of DNS records that perform the vital function of verifying that the email received originates from the purported sender.

DMARC is all about putting in a mechanism to prevent criminals and spammers from being able to create emails that look as if they come from a domain but are fake.

You may have read that the DMARC requirement being rolled out by Yahoo and Google only applies to large mail senders (Over 5,000 per day), but here is the rub.

The threshold will inevitably be reduced, and because larger companies will have complied with DMARC, making faking their email difficult for the Cybercriminals, as a result, inevitably, Cybercriminals will shift their focus to companies who aren’t DMARC compliant, the SMEs.

So my advice is that less Spam is a good thing, and making life more complicated for cybercriminals is in everyone’s interest, whatever size of business we run.

See how we can make your business DMARC-compliant and keep it compliant. Get a free evaluation using our DMARC report analyzer.

Mail Authentication. (The technical stuff)

The first policy update affects your domain architecture. You now must use SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance) to authenticate your emails and prove they’re coming from a legitimate source.


SPF is an email authentication protocol that allows the owner of a domain to specify which mail servers they use to send mail from that domain. SPF records are published in DNS (Domain Name System) records and are used to verify that incoming mail from a domain comes from an IP address authorized by that domain’s administrators.


DKIM is another email authentication protocol that allows the owner of a domain to attach a digital signature to outgoing emails. The signature is verified by the recipient’s mail server, which checks the signature against the public key published in the domain’s DNS records.


DMARC is a protocol that works with SPF and DKIM to authenticate email senders and prevent spoofing and Phishing. Once set up, DMARC ensures that the destination email systems trust messages sent from your domain. Using DMARC with SPF and DKIM gives organizations more protection against spoofing and phishing emails.

Improving email security by implementing DMARC, SPF, and DKIM can leave you with the problem of what to do with DMARC reports.

The UK National Cyber Security Centre provides helpful guidance (Email security and anti-spoofing) on the records you should implement to be compliant and avoid using your domain for spamming and Phishing campaigns.

If you have created a DMARC record, you will know that DMARC provides reports in an XML format that should be monitored to ensure smooth operation.

DMARC report analyzer tools continuously monitor DMARC XML reports to ensure proper authentication of legitimate emails. Large providers, such as Gmail, Outlook, Yahoo, etc., are already implementing DMARC. Your mail servers can receive reports from domains that show the email traffic, including the pass/fail rate of DMARC evaluation, email sources, and other relevant data.

Shadow IT?

One of the issues customers often experience is being unaware of all the email sources working on and within the business.

Often, Invoices or credit control are being performed for the business by a supplier or contractor; you may use Mailgun or Mailchimp for email mailshots.

These sources are often forgotten or were set up by a team within the business without the IT department’s knowledge, a practice known as Shadow IT.

Monitoring is the first step.

When using multiple email-sending sources, each will require its own SPF mechanism to be included in your SPF record; you can quickly exceed the lookups limit and cause a “perm error” result.

By using our DMARC service to manage DMARC and SPF, you can:

  • Have unlimited SPF DNS lookups
  • Optimise your SPF record
  • Add, remove, and update unlimited email service providers
  • Mitigate and avoid outgoing email loss caused by “permerror.”

The answer to what to do with DMARC reports.

Managed DMARC

With Managed DMARC, you can control your DMARC record(s) from your DMARC portal.

With Managed DMARC report analyzer, you can:

  • Manage the DMARC policy of your domains and subdomains on our platform simply and effectively.
  • Manage your RUA and RUF tags. (These reports are converted into data on your dashboard).
  • Manage your SPF and DKIM alignment mode.
  • Investigate what DMARC policy will be applied to your email.
  • Get a configuration overview with email authentication from your email-sending services. DMARC report analyzer tools continuously monitor DMARC XML reports to ensure proper authentication of legitimate emails.

The Impact of DMARC Changes on Spam Filtering:

We can expect the world of Spam filtering to benefit from the changes being made to the landscape of email authentication protocols, specifically the upcoming changes to Domain-based Message Authentication, Reporting, & Conformance (DMARC), which are poised to impact how spam filtering solutions handle email significantly.

Enhanced Email Security:

DMARC’s stricter alignment policies will force senders to authenticate their emails using SPF, DKIM, or both. This significantly tightens the security net, making it harder for spammers to spoof legitimate domains and infiltrate inboxes. Spam filters can leverage these stricter checks to identify and block unauthorized emails more accurately, potentially reducing spam volume.

Improved User Experience:

DMARC changes can enhance user trust and email engagement by reducing spam influx. Fewer unwanted messages translate to cleaner, safer inboxes, streamlining communication and boosting productivity. Additionally, with increased sender accountability, users can feel more confident about the legitimacy of their emails.

Challenges and Considerations:

While DMARC promises a cleaner email ecosystem, its implementation presents particular challenges. The stricter policies might initially increase email bounce rates for legitimate senders who haven’t properly configured their DMARC records. Additionally, spammers will target smaller organisations that haven’t implemented DMARC. Cybercriminals might resort to more sophisticated techniques to bypass authentication protocols, necessitating continuous adaptation and improvement from spam filtering solutions.


The DMARC changes represent a significant step towards a more secure and reliable email environment. While initial challenges exist, the long-term benefits for users and email service providers are undeniable. Spam filtering solutions must evolve to adapt to the stricter authentication protocols. Still, the resulting reduced Spam and improved user experience promise a brighter future for email communication.
