Obtain the "5.7.5 permanent error evaluationDMARC Policy” when sending email from your domain?The "5.7.5 Permanent Error Evaluating DMARC Policy" is a common error that prevents SMTP ports from accepting email from your domain. The problem usually occurs due to a combination of settings in the SPF record, DMARC record, or email service.
In this guide we describe how to solve this problem quickly and easily.
Reasons for 554 5.7.5 Persistent Error Evaluating DMARC Policy
If you are facing "permanent error 5.7.5 evaluating DMARC policy", here are some common reasons for this error:
Incomplete DMARC settings
When configuring DMARC, you can choose to use p=none or p=quarantine/reject. If you use the p=none policy, make sure your SPF and DKIM relay the message. Otherwise, DMARC policy evaluation fails.
Incorrect DKIM email authentication record
DKIM stands for DomainKeys Identified Mail. It is a method of verifying the authenticity of the email sender that prevents malicious actors from impersonating the domain name of the email sender.
Sometimes problems with your DKIM authentication can occur. A mismatch between the "d=" tag in the DKIM signature and the sending domain will cause the DMARC evaluation to fail.
For example, if you changed your domain name and didn't update it in the DKIM records, the DMARC policy evaluation will also fail.
Incorrect SPF record
SPF stands for Sender Policy Framework. It is an email authentication technique used to verify whether an email message came from a valid sender server or not.
DMARC checks SPF records to determine if they are valid or not. You must ensure that SPF records are configured correctly and work with your domain name to avoid this error.
Wrong policy evaluation on receiver side
If the receiving server misinterprets your DMARC policy settings, it can also lead to this error. This means that the receiving server is rejecting emails based on its own policies, not due to an error in its DMARC settings.
To avoid this issue, ensure that all of the above items are properly configured to pass the policy evaluation on the receiver side.
Then talk to the recipient and ask them to rate their own DMARC.
How to fix 554 5.7.5 Persistent error evaluating DMARC policy
1) Remove extra characters from the registry
Error 5.7.5 Persistent error evaluating DMARC policy can be due to many reasons, but the most common are:
- wrong quotes
- additional characters or symbols in the registry
- a missing semicolon at the end of the record
Here is an example of a log where this error occurred:
v=DMARC1; p=none; street=mailto:[email protected]🇧🇷 call=mailto:[email protected]; fo=1:d:s.
At first glance, this record may look good to you, but when we tested it, we got the message "5.7.5 permanent error evaluating DMARC policy".
When we double-checked that, we noticed that there was an extra period at the end of the record—if you look closely at the same record above, you'll see that there's a period (dot) (.) at the end.
After we removed that point and ran the test again, it worked perfectly.
Here's how the same record turned out to be error-free:
v=DMARC1; p=none; street=mailto:[email protected]🇧🇷 call=mailto:[email protected]; fo=1:d:s
2) Change your SPF record from neutral
If you get the error "5.7.5 Permanent error evaluating DMARC policy" when trying to send an email, it's probably because your SPF record is set to Neutral.
SPF stands for Sender Policy Framework and helps ensure that the email server sending an email is legitimate. It's not enough to just have a server that sends email; Verification must be made that the server is legitimate. This is what SPF does: it checks that your mail server has the correct credentials.
Why can't your SPF record be neutral?
Because if messages can be sent through a neutral server, scammers can send fake emails using their domain name, which means people can think they're legit when they're not — and end up clicking on links or files download that shouldn't.
Because of this, you should at least change your SPF record toSoftfail ~ alleorHardfail - alleif you implement DMARC, so people know that a message from your domain name is likely to be safe.
3) Check if your email service provider supports SPF-aligned emails
One of the most common reasons for this error is that your email service provider does not support SPF-aligned emails.
Email providers like MailChimp and ProtonMail have their own SPF records and if you send email through them, they won't send SFP-aligned emails. Therefore, it is important that you check your email service provider's SPF disposition type to see if it supports SPF-aligned emails.
If this is the case, your DKIM signature will be modified during the delivery process to match the From address with your own domain (instead of MailChimp's domain) and ensure you pass the DMARC policy assessment.
Otherwise, you'll need to use a different email service provider (or change your existing provider's settings) to send SPF-targeted email.
4) Change policy p=none to DMARC
If you get the error "5.7.5 permanent error evaluating DMARC policy", it means that your domain's DMARC policy is preventing you from sending your emails. To fix this you just need to change your DMARC record with your DNS provider to have a p=none policy.
The DMARC policy tells email providers what to do with emails that fail SPF and DKIM checks: reject them or quarantine them. If you want to send email even if these checks fail, you can temporarily relax your policy by setting it top=nonein your DNS settings.
This is known as a "relaxed policy" and is not recommended to prevent email spoofing. However, if you change your DMARC policy to p=none, you can temporarily send emails without receiving DMARC errors.
For example, you can change this record:
_dmarc.pseuddomain.com TXT „v=DMARC1; p=ablehnen; fo=1
Therefore:
_dmarc.pseuddomain.com TXT „v=DMARC1; p=three; fo=1
What does that mean for you? You can send your email even if it doesn't pass DMARC. However, you want to revert to a p=reject or p=quarantine policy to prevent email spoofing on your domain.
5) Configure DomainKeys Identified Mail (DKIM) authentication
If you're getting the error message "5.7.5 permanent error evaluating DMARC policy", it means you don't have DomainKeys Identified Mail (DKIM) email authentication enabled on your domain - and to pass DMARC, you must have a DKIM email authentication record configuration.
To do this you need to do the following:
- On the Account Settings page, select I will manage my email authentication.
- Enter the domain name in the DKIM field and click Save.
- Copy the generated TXT record name and TXT record value to the web host's DNS records
Formatting Requirements for DMARC Policies
DMARC is an email authentication protocol that allows recipients to verify that emails claiming to come from your domain are actually from your domain. This guide describes some of the important formatting requirements when setting up DMARC for the first time.
➤ First, your DMARC entry must start with "v=DMARC1". This lets email providers know that the record is formatted according to the currently used DMARC version (which is 1).
➤ Then provide your policy. The policy must be p=none or p=quarantine or p=reject. This tells email providers what to do when an email fails authentication checks.
➤ The policy must be the second value in the registry. The policy can be one of three things: p=none, p=quarantine, or p=reject. "None" means you don't want the email provider to do anything if they see a suspicious email from your domain - they'll just leave it alone and possibly even deliver it. "Quarantine" means that you want suspicious email from your domain to be delivered as spam or junk instead of being delivered as regular email. Finally, "reject" means you want suspicious emails from your domain to be rejected and never delivered.
➤ Use colons as separators between values - it's a good idea to use a colon and not a semicolon. Semicolons can cause problems, especially when specifying multiple values on a single line.
➤ Don't use extra characters or wrong quotes. Excess white space at the end of a line is treated as part of the record, which can cause problems.
Here is an example of a good DMARC record:
v=DMARC1; percent = 100; p=reject; street=nearby:[email protected]; die Email:[email protected]; aspf=s
How to find errors in DMARC registration policy
A DMARC record is a good step towards securing your email communications. However, if there is a mistake in it, the whole system becomes ineffective. It is therefore important to find and fix errors as quickly as possible.
This works best with theDMARC searchPowerDMARC tool. The tool checks whether your registration is valid or not and displays possible errors. You can use the tool for free by following these steps:

FAQs
What happens if DMARC policy is not enabled? ›
The error message “DMARC Policy Not Enabled” means your DMARC policy is active but set to “none” which means it cannot take action with any unauthorized emails. To fix this, modify your policy mechanism (p) from p=none to p=reject/quarantine.
What is a DMARC PermError? ›It signifies that DMARC could not correctly interpret the domain's published records, and signals an error condition that requires immediate DNS intervention to be resolved.
How do you want to treat mail that fails the DMARC check? ›The DMARC error message above has a p=reject or p=quarantine. This will prevent emails that fail DMARC to be sent to the Inbox folder. To make sure messages are delivered even if DMARC fails, you will want to change the policy in your DMARC to p=none with your DNS provider.
How do I fix 5.7 5 permanent error evaluating DMARC policy? ›If you're getting a “554 5.7. 5 permanent error evaluating DMARC policy” error, it means that the DMARC policy on your domain is preventing you from sending your emails. To fix this, you just need to change your DMARC record with your DNS provider to have a p=none policy.
What causes a DMARC failure? ›When an email fails DMARC authentication, it means that the sender's address does not match the purported sender's domain. This can happen for a number of reasons, but the most common cause is that the email was sent from a forged or spoofed IP address.
How do I activate my DMARC policy? ›- Step 1: Identify valid sources of mail for your domain.
- Step 2: Set up SPF for your domain.
- Step 3: Set up DKIM for your custom domain.
- Step 4: Form the DMARC TXT record for your domain.
While DMARC isn't specifically a website vulnerability or 'bug', not having it fully configured does make your domain – and organization – extremely vulnerable to impersonation and phishing attacks, such as BEC.
How do I enable DMARC policy is not enabled? ›- Go to the DNS management console.
- Navigate to the records section and find the DMARC record.
- Update the record and set a Quarantine or Reject policy.
This error means that the message failed authentication tests and is not DMARC Compliant. A DMARC Compliance failure means that both SPF & DKIM verification tests failed. These failures can negatively impact email delivery as inboxes cannot verify the legitimacy of your email.
How do I reject emails that fail DMARC in Office 365? ›- Send a legitimate email.
- Send a spoof email.
- Let's create the mail flow rule.
- Let's send another legitimate email to make sure that everything is working as expected.
- Finally, let's send another spoof email.
How do I disable DMARC? ›
You will continue receiving DMARC reports, as long as you have specified an email address in 'rua=mailto:' field of the DMARC DNS entry. Simply remove the corresponding Report-only mode DMARC entry from your domain DNS records.
What happens if DMARC record is missing? ›When you see “No DMARC record found” or “DMARC record not found” or “DMARC record is missing” that means your domain misses the most effective and powerful email authentication mechanism such as DMARC. A domain without a DMARC reject policy is not nice, sort of like being naked in the middle of the street.
What happens if DMARC is set to reject? ›Implementing a DMARC Reject Policy
A DMARC "p=reject" policy will allow you to ensure that all malicious email is stopped. As an added bonus, the recipient of the intended malicious email will never become aware of the email in the first place, as it will never get sent to a spam or quarantine folder.
This is actually acceptable when you very first deploy DMARC, so you can just set up monitoring and make sure everything works. However, once you're sure that everything is working correctly, you should set your policy to reject in order to protect your domain's reputation and safeguard recipients against fraud.
What is a DMARC policy? ›DMARC is an email authentication protocol to prevent fraudsters from spoofing your domain that works with SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) to verify the authenticity of the email.
Do I need a DMARC policy? ›You can use DMARC to protect your domains against abuse in phishing or spoofing attacks. As a website owner, you want to know for sure that your visitors or customers will only see emails that you have sent yourself. Therefore, DMARC is a must for every domain owner.
How do I know if my DMARC is correct? ›DMARC Record Check is free and easy to use. Just enter the domain name to perform the DMARC check. The DMARC Record Check will then parse the DMARC record and displays the DMARC record along with additional information. Use the DMARC Record Check to test and lookup the DMARC record.
What is DMARC policy in email? ›DMARC is a standard email authentication method. DMARC helps mail administrators prevent hackers and other attackers from spoofing their organization and domain. Spoofing is a type of attack in which the From address of an email message is forged.
Is DMARC set on Google? ›DMARC is enabled at your domain host provider, not in your Google Admin console. So you'll need the sign-in information for your domain host account.
Does DMARC affect incoming email? ›Setting up DMARC for inbound emails means that the email service provider (ESP) will be able to identify incoming messages and filter them, so that only those messages containing a From address that matches the IP address of your current domain or subdomain are delivered to the inbox.
How do I make my email DMARC compliant? ›
For email to be considered DMARC compliant, the policy domain (Header. FROM) should match either the SPF domain or the DKIM domain. This is called identifier alignment. The alignment can be specified in either strict mode (an exact match) or relaxed match (match of organizational domain).
How do I enable DMARC in Gmail? ›- Go to the Google Admin Toolbox and select the Dig feature.
- In the Name field, enter _dmarc. followed by your complete domain name. ...
- Below the Name field, click TXT.
- Verify your DMARC TXT record name in the results.
DMARC reports are usually sent once a day by email. They're sent to the email addresses you specify when you define your DMARC record. If reports are turned on with the rua DMARC record tag in your DMARC record, every server that receives mail from your domain sends a report.
Why is Microsoft 365 blocking my emails? ›Microsoft 365 puts a block on sending “bulk email” because if your computer or your email account is compromised the criminals are likely to try to email all your contacts.

There are two known implementations: Refuse to accept non-compliant email at SMTP time. This is the preferred and most widely adopted implementation because delivery to DMARC verifying receivers is prevented.
What does DMARC stand for? ›DMARC, which stands for “Domain-based Message Authentication, Reporting & Conformance”, is an email authentication, policy, and reporting protocol.
Can DMARC block emails? ›DMARC takes it a step further and gives you full control to set a policy to reject or quarantine emails from sources you do not know or trust, all based on the results of DKIM and SPF.
Is DMARC policy important? ›Properly configuring DMARC helps receiving mail servers determine how to evaluate messages that claim to be from your domain, and it is one of the most important steps you can take to improve your deliverability.
What is DMARC and do I need it? ›Domain-based Message Authentication Reporting and Conformance (DMARC) is a free and open technical specification that is used to authenticate an email by aligning SPF and DKIM mechanisms. By having DMARC in place, domain owners large and small can fight business email compromise, phishing and spoofing.
