Google, in their recent security blog has confirmed that they are all set to take their email security to next level by rolling out Gmail’s general support of BIMI, an industry standard that aims to drive adoption of strong sender authentication for the entire email ecosystem.

Almost an year after they first announcing the adoption Brand Indicators for Message Identification (BIMI) pilot , this roll out is going to be next big step in email security. BIMI provides email recipients and email security systems increased confidence in the source of emails, and enables senders to provide their audience with a more immersive experience by displaying the Brand logos as an icon next to email senders’ names, on every email they send.

With Google announcing their BIMI support, the community has got even bigger with other industry leading mail service providers like Yahoo(Verizon Media), Fastmail and now Google.

According to the standard to adopt BIMI for a mail domain, it must first be secured by DMARC in Quarantine/Reject policy.  This would ensure the logo are not being displayed on any unauthenticated email.

How does DMARC help?

To explain in short, DMARC – developed in 2012, is a protocol that uses both SPF and DKIM authentication to secure email, and additionally has a mechanism that sends the domain owner a report whenever an email fails DMARC validation. This means the domain owner is notified whenever an email sent by an unauthorized third party.

Every new invention brings its new challenges. Every new challenge pushes us to find a new way to overcome it. DMARC has been around for some years now, still phishing has existed for much longer. As new organizations are born each day, email security is important and plays a vital role in every organization and there should be necessary actions taken to make sure there is no security breach. It becomes the responsibility of every business to protect themselves, their clientsb and employeesb sensitive personal information.

At ProDMARC, we’re here to help you meet this new challenge with ease.! ProDMARC as a product built on a mission to achieve a secure and spoofing free email channels across all of internet space; makes reporting of DMARC, providing volumes and trends of the outbound mails including that of phishing campaigns and yield confirmation for reliability of the outbound mails in terms of SPF, DKIM & DMARC conformance; smooth and uncomplicated.

Summarizing, ProDMARC helps improve customer and third party trust in email communications.

Why Are My Emails Going To Spam, And How To Fix It?

Email concept with laptop spam and virus computer monitor internet security concept, businessman reading electronic mail with a laptop. Spam, junk and e-marketing on screen, Spam Email Pop-up Warning.

Are you frustrated with your emails going to spam? If the answer is yes, then you must check out this article. Here you will explore six ways that can help you to fix the problem. So, keep reading.  

If email is the main communication channel for your business, then email going to spam can make you yell at your computer. We can understand how irritating it can be to send an email, and not have the recipient open it since accessing the spam box is not a daily habit. 

Before exploring the solution to this issue, we need to identify the problems.

Why are my emails going to spam?

According to Statista, half of all emails are spam. Email is a robust platform for communication for every person. And email spam is a serious concern that we face today. Email spam is rising as a severe problem on the internet today. Almost every email service provider has implemented some controls to solve the problem of Spam.

The email filters are designed so that users don’t have to remove the spam message manually. There can be many reasons behind your email going to spam. Here is the reason behind spam issues-

1. You haven’t set up proper authentications 

One of the biggest reasons behind email going to spam is failure to comply with email sender authentication standards. There are three major email sender authentication standards namely DMARC, DKIM, and SPF. To ensure the mails are appropriately delivered in Inbox, you should ensure the email comply with the authentication standards. 

2. Your IP address was used for sending spam emails

These issues are mostly seen among businesses. If you have taken your IP address from an internet service provider, then the possibility of your IP address being used for sending spam by older users in the past may be quite high. 

3. Subject lines that can be misleading to recipients

Email providers like Gmail use spam channels to attempt to keep spam out of inboxes. One technique is to filter the email by its subject line. Assuming the spam channel sees too many spammy words, your email may be singled out as spam and get sent to the spam or junk folder.

Some of the examples of spam words are-

  • Free Gifts 
  • Click here
  • As seen on 
  • Dear friends 
  • Information you requested 
  • Save Big 
  • Cash

4. The number of inactive email addresses on your list is too many

Over the long run, a portion of the email addresses on your database may get latent. Notwithstanding, if this happens, your email list can be loaded with inert clients. In that case, your email will remain unopened in large numbers, which can cause email channels to label it as spam.

How Can You Fix Your Email Spam Problem?

Now that you know about the reason that is causing the problem let us look at how you can solve the problem. 

1. Set up proper authentications 

Recently, spam channels are putting more weight on sender notoriety instead of simply the substance of your messages. The content of your email matters; however, somebody with an authentic email address could pull off some spam-contiguous content that a sender with an inauthentic email domain standing can’t. The ideal approach to improve your credibility is to ensure you’re appropriately checking your messages with authentication tests like DKIM and SPF. In terms of authentication, applying these DMARC checks is the best way to securely validate your emails.

If you’re utilizing free email providers like Gmail, you don’t have to stress over this. This possibly applies if you’re using a custom email address. You can set up these validation tests by adding TXT records in your organization’s DNS server for the executives. You can get the DMARC record that you need from your email provider. 

2. Follow email configuration/same accepted procedures when sending messages

Once you have completed DMARC implementation, you are one step closer to avoiding the spam folder. You should also follow the following points:

  • Don’t use any abusive/obscene images 
  • Try to ignore spam copy
  • Avoid unnecessary attachments 

Final Thoughts 

We’ve already established that there can be various reasons for email spam issues. The best solution to this problem is proper authentication. If you are opting for DMARC authentication, you should follow its DMARC policy.  If you fail to complete valid authentications, you will stand as a malicious sender in front of the email spam filter.

How to setup DMARC in 3 easy steps

Metal gear wheels on a computer keyboard.

DMARC (Domain-based Message Authentication, Reporting, and Conformance) is a method of ensuring the authenticity of an email sent from a specific domain.

Regrettably, this critical email security feature is not enabled by default for every domain, web host, or email server. Organizations and email administrators must establish and set up policies for DMARC.

We’ll go over how to set up a simple DMARC configuration on your own domain in this blog. The process includes 3 simple steps to optimally configure your email server to send signed emails.

Step 1. Generate a DMARC record

A DMARC record is a short snippet of code that is published to the DNS to tell the mailbox service provider how to handle an incoming email that fails authentication, based on the results of the SPF and DKIM checks.

DMARC records are text (TXT) resource records (RR) that are published in the DNS and tell an email receiver what to do with non-aligned emails it receives.

Consider an example DMARC record for the domain “sender.exampledomain.com” that reads: v=DMARC1;p=reject;pct=100;rua=mailto:postmaster@exampledomain.com

Log in to the DMARC dashboard to create a DMARC record for your secured company domain. Then navigate to DNS Records -> Publish DMARC Record and copy the excerpt displayed in orange on the page. 

For the test domain DMARC site, here’s a sample DMARC entry:

v=DMARC1; p=quarantine; rua=mailto:reports@dmarc.site; ruf=mailto:reports@dmarc.site; adkim=r; aspf=r; rf=afrf

  • For email whose breaches policies should be handled, the “p” option provides three options: none, quarantine, or reject.
  • The adkim and aspf parameters specify how stringent the DKIM and SPF policies should be implemented, with ‘s’ denoting strict and ‘r’ denoting relaxed.
  • The RUA provides an address for aggregate data reports, while the RUF provides an address for forensic reports

Step 2. Publish the DMARC record to DNS

Now that you have the DMARC record, publish it to the DNS so that email service providers can use it to run DMARC checks.

To do so, go to your DNS management interface and choose the domain for which you want to publish the DMARC record, such as mydomain.com.

Create a TXT entry with the following settings on mydomain.com:

Type: TXT

Host: _dmarc

TXT Value: (DMARC record generated above)

TTL: 1 hour

For instance, here is how it appears in GoDaddy’s DNS administration console:

It can take up to an hour for the DMARC record to become accessible after it has been published (usually much faster). You can then use the DMARC Checker tool to double-check if it was correctly published.

Step 3. Analyze aggregate reports

Every day, many email service providers send out aggregate reports. This means you might get aggregate reports the day the DMARC record is published.

However, your first aggregate reports could take up to 72 hours to come. Once you get the information, you must utilize it to correct your email streams.

Conclusion

Large enterprises have been able to reduce phishing-based brand impersonations to near nil utilizing automated DMARC implementation tools like ProDMARC. 
This not only protects the brand’s reputation and the effectiveness of revenue-generating email campaigns, but it also protects employees, customers, partners, and the general public from expensive email frauds. Get in touch with us to discover our email authentication solutions.

What is DMARC evaluation?

Businesswoman use laptop ,analytics and financial and bank technology concept, chart from computer laptop,Business growth concept

DMARC (Domain-based Message Authentication Reporting and Conformance) is an email validation system that prevents your company’s email domain from being exploited for email spoofing, phishing scams, and other forms of cybercrime. SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) are two current email authentication systems that DMARC uses.

When a domain owner adds a DMARC record to their DNS record, they will be able to see who is sending email on their behalf. This data can be utilized to obtain more specific information about the email channel. A domain owner can get control over emails sent on his behalf using this information. DMARC can be used to defend your domains from phishing and spoofing attacks.

What is a DMARC record?

A DMARC record is stored in the DNS database of a company. A DMARC record is a properly structured DNS TXT record with a specific name, such as “_dmarc.mydomain.com” (note the leading underscore). The following is an example of a DMARC record:

dmarc.mydomain.com. IN TXT “v=DMARC1\; p=none\; rua=mailto:dmarc-aggregate@mydomain.com\; ruf=mailto:dmarc-afrf@mydomain.com\; pct=100”

Reading left-to-right in plain English, this record says:

v=DMARC1 specifies the DMARC version

p=none specifies the preferred treatment, or DMARC policy

rua=mailto:dmarc-aggregate@mydomain.com is the mailbox to which aggregate reports should be sent

ruf=mailto:dmarc-afrf@mydomain.com is the mailbox to which forensic reports should be sent

pct=100 is the percentage of mail to which the domain owner would like to have its policy applied

DMARC record check

A genuine DMARC record must be published before DMARC implementation. We offer a free tool called DMARC Record Check that displays the DMARC record, tests it, and verifies that it is genuine. The DMARC Record Check tool is both free and simple to use. To do a DMARC check, simply input the domain name.

After that, the DMARC Record Check parses the DMARC record and displays it along with other information.

To test and lookup the DMARC record, use the DMARC Record Check. Then assess each potential alternative as well as the ones that have been implemented. If there are any external domains in use, DMARC Record Check will verify and test them.

Results of a DMARC Check

A DMARC test performed with DMARC Record Check will test and declare the following tags.

v-Version of the DMARC protocol. 

p-This policy should be used for emails that fail the DMARC check. It might be “none,” “quarantine,” or “reject.” To gather the DMARC report and acquire insight into the current email flows and their state, the value “none” is utilized.

rua- A list of URIs for ISPs to send XML feedback to. NOTE: this is not a list of email addresses. DMARC requires a list of URIs of the form “mailto:test@example.com”.

ruf- ISPs can transmit forensic information to a list of URIs. Please note that this is not an email address list. A list of URIs in the format “mailto:test@example.org” is required by DMARC.

rf- Forensic reports are written in this format. This might be “afrf” or “iodef.”

pct- The percentage tag tells ISPs that the DMARC policy should only be applied to a certain percentage of failed emails. “pct=50” instructs receivers to use the “p=” policy only 50% of the time when dealing with emails that fail the DMARC check. NOTE: This will only work with the “quarantine” or “reject” policies, not the “none” policy.

adkim- The “Alignment Mode” for DKIM signatures can be “r” (Relaxed) or “s” (Strict) (Strict). Authenticated DKIM signature domains (d=) that share an Organizational Domain with an email’s “From” domain will pass the DMARC check in Relaxed mode. Strict mode necessitates a precise match.

aspf- SPF’s “Alignment Mode,” which can be either “r” (Relaxed) or “s” (Strict) (Strict). The DMARC check will pass in Relaxed mode for authenticated SPF domains that share an Organizational Domain with the email ‘From’ domain. A precise match is necessary in Strict mode.

sp- If a sub-domain of this domain fails the DMARC check, this policy should be enforced. Using this tag domain owners can publish a “wildcard” policy for all subdomains.

fo- Options for forensics. Allowable values: “0” to generate reports if both DKIM and SPF fail, “1” to generate reports if either DKIM or SPF fails to deliver a DMARC pass result, “d” to generate reports if DKIM failed, and “s” to generate reports if SPF failed.

ri- When the aggregate XML reports are sent, this is the reporting interval. This is a personal preference, and ISPs may (and very certainly will) transmit the report at different times (normally this will be daily).

What does DMARC compliance mean?

An organization can pass the DMARC check and become DMARC compliant by authenticating email channels with DKIM and/or SPF. DKIM and/or SPF must be aligned to become DMARC compliant. Only DKIM or SPF must be configured to be DMARC compliant.

How to Publish a DMARC Record

Submitting Online Internet Loading Progress Website Concept

A DMARC record is part of your Domain Name System (DNS) record, which is responsible for routing Internet traffic. Additional information, such as your domain’s DMARC record—a text entry within the DNS record that informs the world about your email domain’s policy based on the specified SPF and DKIM protocols—can be included in the DNS.

Set up a DMARC record for each domain you want to monitor before you can start generating and visualizing DMARC data. You can use our DMARC generator if you need help setting up your DMARC record.

Prerequisites Before creating DMARC record

Before creating DMARC records it’s a good idea to test DKIM and SPF. 

  • Creating an SPF record
  • Creating a DKIM record

Create the record

DMARC is a system which allows email recipients to make better decisions depending on the reputation of the sender domain. It provides a platform for the sending side to publish policies to improve spam and phishing efficacy, essentially developing domain reputations. This aids in the provision of recommendations for dealing with messages that do not conform to the policies provided by the sender domain.

DMARC is aimed at:

  • Reducing false negatives
  • Providing authentication reports
  • Applying sender policies at the receiving end
  • Reducing phishing
  • Being scalable

An SPF and DKIM record must be published on the transmitting domain before DMARC may be used. You can configure DMARC by adding policies to your domain’s TXT records once the SPF and DKIM records are in place (the same way in which you published your SPF and DKIM records). Your TXT record name should read something similar to “_dmarc.your_domain.com.” Please replace the “your_domain.com” with your own domain.

Since DMARC policies are published as TXT records, they specify what an email recipient should do when it receives non-aligned messages.

When establishing a TXT record, the name of a DMARC record is “_dmarc,” which generates a TXT record like _dmarc.mydomain.com or _dmarc.mydomain.net.

Example:

“v=DMARC1;p=reject;pct=100;rua=mailto:postmaster@dmarcdomain.com” 

In this scenario, the sender defines the policy as such that the receiver outright rejects all non-aligned messages and sends a report about the rejections to a specific email address. If the sender were to use the “quarantine” setting in the policy, it would look like:

“v=DMARC1;p=quarantine;pct=100;rua=mailto:postmaster@dmarcdomain.com”

and would request the action to quarantine on the receiving end of the message. In the next example, if a message claims to be from your domain.com and fails DMARC, no action is taken. Instead, these messages will then show up in your daily aggregate report sent to

“v=DMARC1; p=none; rua=mailto:postmaster@your_domain.com”

Here is a sample where the message fails DMARC, then quarantines it 5% of the time.

“v=DMARC1; p=quarantine; pct=5; rua=mailto:postmaster@your_domain.com”

In this sample, the policy is set to reject the message 100% of the time and send the daily report to the specified address of dmarc@your_domain.com.

“v=DMARC1; p=reject; rua=mailto:postmaster@your_domain.com, mailto:dmarc@your_domain.com”

DMARC Implementation

Since the DMARC configuration recognizes that scaling out the deployment all at once can be difficult for certain organisations, there are some built-in methods for “throttling” the DMARC processing so that complete deployment can be achieved in stages over time.

The first step is to keep an eye on your traffic and reports. Assess the vulnerabilities (where messages are sent without being digitally signed or from invalid source IP addresses) and use SPF and DKIM records to address them.

As you become more comfortable with the findings from your regular aggregate reports, you will adjust the action on your policies to start quarantining. You can do this by using DMARC to change your TXT record to use the “quarantine” action. Monitor your daily reports.

Once you’ve been tracking your traffic and regular reports for a while and are certain that the sources seen sending traffic on behalf of your domain are all digitally signed, you can proceed to the next phase, which is modifying the policy to use the “reject” tag to completely deploy DMARC. Monitoring the files and spamfeed is an important component of maintenance.

It is also worth noting that the pct tag, which is optional, can be used to sample your DMARC implementation in increments. Since 100% is the norm, setting “pct=20” in your DMARC TXT record causes one-fifth of all messages affected by the policy to receive the disposition rather than all of them. When you want to quarantine and reject mail, this setting is particularly useful. Start with a lower percent to begin with and increase it every few days.

A conservative deployment cycle would resemble:

  1. Monitor all.
  2. Quarantine 1%.
  3. Quarantine 5%.
  4. Quarantine 10%.
  5. Quarantine 25%.
  6. Quarantine 50%.
  7. Quarantine all.
  8. Reject 1%.
  9. Reject 5%.
  10. Reject 10%.
  11. Reject 25%.
  12. Reject 50%.
  13. Reject all.

Delete the percentages from your policies when you are about to finish the DMARC deployment so that the full action of “quarantine” and “reject” is now working at 100%. 

Conclusion

After you have published DMARC records, DMARC data will start to be created in the form of reports within a day or two, giving you insights into how your domains handle email. These reports are based on XML and might be difficult to read and comprehend for humans.

If you receive a lot of reports, you will quickly realize that manually posting them every day is not feasible. ProDMARC specializes in processing these reports and determining the measures that must be taken in order for DMARC to be distributed more simply throughout an organization.

SPF, DKIM and DMARC: Are they mere acronyms or Useful Email Security?

Shield Icon Cyber Security, Digital Data Network Protection, Future Technology Digital Data Network Connection Background Concept.

Since the early days of the internet, spam has been a persistent and chronic problem. Gary Thuerk of Digital Equipment Corp (DEC) sent the first unsolicited mass e-mailing (later dubbed SPAM) on May 1, 1978, advertising the VAX T-series to 400 of the then 2600 ARPAnet users.

The SMTP email protocol, which we still use today, evolved from these early ARPANET mail protocols (Postel RFC788 and RFC821) in the early 1980s, and has changed very little since then. The SMTP protocol has had little to no security built in since its introduction, and when used to send email, it offers little defense against spoofing of email addresses or servers. However, several new tools have recently been added to the email security arsenal to protect against these threats.

SPF, DKIM, and DMARC are all similar features for detecting spoofed or spam emails, but they vary slightly.

SPF (RFC 7208)

SPF (Sender Policy Framework) specifies a list of servers that are permitted to send email for a particular domain using a DNS entry. Its security is based on the fact that only authorized domain administrators have access to the DNS zone records for the domain.

DKIM  (RFC 6376)

DKIM (DomainKeys Identified Mail) differs from SPF in that it verifies that the receiving server is allowed to send mail for the domain and that the quality of the mail has not changed since it was sent. Using DKIM keys stored in DNS and DKIM uses a public/private key signing mechanism.

The following steps are applied to the email process with DKIM:

  • Sending servers create a signature with their DKIM private key and insert it into the email header (DKIM-Signature).
  • Email recipients look up the DKIM public key in the sending domain’s DNS TXT record, which is then used to verify the DKIM-Signature attached to the email.

If the email body content is modified, the email signature will no longer match and validation will fail.

This process verifies that the email content has not been tampered with, as well as that the email was sent from a domain-approved server.

DMARC  (RFC 7489)

DMARC (Domain-based Message Authentication, Reporting, and Conformance) incorporates elements of both SPF and DKIM by stating a simple DMARC policy that can be used in both tools, as well as allowing the domain administrator to set an address that can be used to submit information about forged mail message statistics gathered by receivers against the same domain, for example:

  • Relative levels of spoofing of your domain(s).
  • Who is spoofing email purporting to be from your domain?

Does that mean your spam problem is resolved?

In an ideal world, all email servers would use these techniques, and SPAM would be significantly reduced. However, since making a mistake in configuring the necessary DNS TXT records can result in the loss of important emails, some domain owners have been hesitant to implement the methods. 

Despite this, major email domain owners such as Google, Microsoft, and Yahoo have implemented these approaches.

SPAM can still be transmitted via compromised accounts and servers, shared hosting email servers, and misconfigured servers, so multilevel email protection is the only way to ensure a clean and safe email feed.

How effective are DMARC, SPF, and DKIM?

These tools will undoubtedly have a significant effect on the fight against SPAM, and the more domains that use them, the better. However, caution should be exercised during DMARC implementation to ensure that all settings are right before going live. SPF, for example, allows you to set the changes in a test mode, which means that recipient domains will not block any mail that fails the test.

How can you block email based impersonation and phishing attacks with DMARC?

Hacker in front of his computer

It is a well-known fact that in most of the cyber-frauds, the cyber criminals impersonate trusted identities, mainly because the chances of the victim falling for such emails are high. These attacks are commonly called as email spoofing.

Let us look at some quick facts about email spoofing attacks:

  1. Over 70% of fraudulent emails are directly sent from a domain name of the victim organisation.
  2. According to a latest email security risk assessment, there is a surge in email spoofing attacks by over 22% as compared to previous quarter.

These attack types are highly sophisticated and it requires us to take a multi-layered approach to detect and stop such attacks

Types of Impersonation Attacks

The email spoofing attacks most commonly used for targeting the dependent parties of the organisation like their customers, partners and associates. The victims might be able to differentiate such emails from legitimate emails and might fall for such attacks

Another major attack exploiting identity theft is CEO/CFO frauds. Here the employees are tricked to make payments to fraudsters account or share confidential information of the organisation.

Why DMARC?

The only way to protect your dependent parties from falling for such attacks is to protect your mailing domain with Domain-based Message Authentication, Reporting & Conformance (DMARC) security control. It works by prohibiting anybody except expressly approved senders from using an organization’s domain (including internal and third-party mailing systems) to send an email. Additionally, DMARC reports also helps you to identify and appropriately configure all your legitimate email senders and also to visualize the threat targeting the organisation’s domain.

How does ProDMARC help you in DMARC journey?

ProDMARC is built on a mission to achieve a secure and spoofing free email channels across all of internet space; makes reporting of DMARC, providing volumes and trends of the outbound mails including that of phishing campaigns and yield confirmation for reliability of the outbound mails in terms of SPF, DKIM & DMARC conformance; smooth and uncomplicated. It helps in gaining visibility on your email domain getting used on your behalf by third parties. It’s important to gain visibility of unauthorized emails which might be getting sent from your brand; ensures that emails do not get blocked due to misconfigurations, making the best use of the customer email communication; generates actionable threat intelligence feeds for your security and transaction monitoring systems helping to block targeted attacks proactively and also helps in identification of lookalike domains for your brand.
