Reasons behind 554 5.7.5 Permanent Error Evaluating DMARC Policy
Impact of SPF and DKIM on DMARC policy evaluation
DMARC relies on SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) for email authentication. SPF verifies the sender's IP address, while DKIM verifies the integrity of the email's content. Both SPF and DKIM records need to be correctly configured to ensure accurate DMARC policy evaluation.
Incorrect SPF Record
SPF (Sender Policy Framework) is another critical component of email authentication that affects DMARC policy evaluation. An incorrect SPF record can contribute to the occurrence of the "554 5.7.5 Permanent Error Evaluating DMARC Policy" error.
Understanding SPF and its role in email authentication
SPF helps verify that the sender's IP address is authorized to send emails on behalf of a specific domain. The SPF record is a DNS TXT record that lists the IP addresses or hostnames authorized to send emails for the domain. When an email is received, the recipient server checks the SPF record to ensure that the sender is authorized to send emails for the given domain.
Importance of correctly configuring SPF records
Misconfigured SPF records, such as missing or incorrect entries, can lead to email authentication failures and trigger the "554 5.7.5 Permanent Error Evaluating DMARC Policy" error. It is crucial to ensure that the SPF record is accurately configured to include all authorized senders.
Impact of misconfigured SPF records on DMARC policy evaluation
DMARC policy evaluation heavily relies on SPF records. Misconfigured SPF records can result in failed authentication, leading to DMARC policy failures and triggering the "554 5.7.5 Permanent Error Evaluating DMARC Policy" issue.

DKIM, an email authentication method, plays a crucial role in DMARC policy evaluation. An incorrect DKIM record can trigger the "554 5.7.5 Permanent Error Evaluating DMARC Policy" issue. It is essential to understand the significance of DKIM and address common issues associated with DKIM authentication.
Definition and significance of DKIM
DKIM adds a digital signature to outgoing emails, allowing the recipient server to verify the email's authenticity. This signature is added as a DKIM signature header field in the email's header. The recipient server uses the public key published in the DNS to validate the DKIM signature, ensuring the email has not been modified during transit.
Common issues with DKIM authentication
Various issues can arise with DKIM authentication, leading to the "554 5.7.5 Permanent Error Evaluating DMARC Policy" error. One common issue is a mismatch between the "d=" tag in the DKIM signature and the sending domain. It is essential to ensure that the DKIM signature aligns with the domain from which the email i
Mismatch between "d=" tag and sending domain
A mismatch between the "d=" tag in the DKIM signature and the sending domain can result in failed authentication. Ensure that the DKIM signature aligns with the domain from which the email is sent to prevent authentication errors.
Incomplete DMARC Settings
Incomplete or misconfigured DMARC settings can lead to the "554 5.7.5 Permanent Error Evaluating DMARC Policy" issue. DMARC, which stands for Domain-based Message Authentication, Reporting, and Conformance, is an email authentication protocol. Incomplete DMARC settings may include not specifying the policy (p=none, p=quarantine, or p=reject) or failing to include the necessary SPF and DKIM records.
For additional insights on DMARC policies, consider exploring the resources available at Global Cyber Alliance.
Explanation of p=none and p=quarantine/reject policies
The DMARC policy specifies how email servers should handle messages that fail authentication. The policy can be set to p=none, p=quarantine, or p=reject:
- The p=none policy allows emails to pass even if they fail authentication.
- The p=quarantine policy directs emails that fail authentication to the spam or quarantine folder
- The p=reject policy outright rejects the email.
Wrong Policy on Recipient Side
In addition to the sender's DMARC policy, the recipient server's policies can also impact DMARC evaluation. It is essential to understand how the recipient server's policies influence the evaluation process and how to ensure proper configuration for successful DMARC policy evaluation.
How the recipient server's policies can affect DMARC evaluation
The recipient server may have its own policies and settings that impact DMARC evaluation. These policies can include rules for handling emails that fail authentication, such as redirecting them to the spam folder or rejecting them altogether. Understanding and aligning with the recipient server's policies is crucial for successful DMARC policy evaluation.
Ensuring proper configuration to pass policy evaluation on the recipient side
To ensure successful DMARC policy evaluation on the recipient side, it is essential to comply with the recipient server's policies. This may involve collaborating with the recipient to understand their policies and aligning your email authentication settings accordingly.
Collaboration with the recipient to evaluate their own DMARC policies
Engaging in a collaborative approach with the recipient can help resolve the "554 5.7.5 Permanent Error Evaluating DMARC Policy" issue.
How to Fix 554 5.7.5 Permanent Error Evaluating DMARC Policy

Check If Your Email Service Provider Supports SPF Aligned Emails
Some email service providers may not support SPF-aligned emails, which can result in the "554 5.7.5 Permanent Error Evaluating DMARC Policy" error. Checking the capabilities of your email service provider and making necessary adjustments is crucial.
Identifying if the email service provider supports SPF-aligned emails
Reach out to your email service provider to determine if they support SPF-aligned emails. They should be able to provide you with information regarding their email authentication capabilities.
Adjusting email service provider settings or considering alternatives for SPF alignment
If your email service provider does not support SPF-aligned emails, you may need to explore alternative options. Consider migrating to an email service provider that supports SPF alignment or adjust the settings within your current provider to ensure SPF alignment.
Example of an SPF record:
An SPF (Sender Policy Framework) record is a type of DNS (Domain Name System) record that identifies which mail servers are permitted to send email on behalf of your domain. Here is an example of an SPF record:
v=spf1 ip4:192.0.2.0/24 ip4:198.51.100.0/24 include:example.com -all
This SPF record means:
v=spf1:This specifies the version of SPF being used.ip4:192.0.2.0/24:This allows all IP addresses from 192.0.2.0 to 192.0.2.255 to send emails for the domain.ip4:198.51.100.0/24:This allows all IP addresses from 198.51.100.0 to 198.51.100.255 to send emails for the domain.include:example.com: This specifies that the SPF record of example.com should be included. Emails sent from IP addresses authorized by example.com are also considered valid for this domain.all: This means that all other servers are not authorized to send emails on behalf of the domain, and such emails should be rejected.
To create or update an SPF record for your domain, you need to log in to your domain's DNS management console and add or edit the TXT record for your domain with the appropriate SPF information.

Setting up or reviewing your Digital Signatures (DomainKeys Identified Mail - DKIM) Authentication
%20(1).png)
Implementing DKIM email authentication is crucial to resolve the "554 5.7.5 Permanent Error Evaluating DMARC Policy" issue. You will need one DKIM DNS record per third party app you are using.
Importance of DKIM email authentication for passing DMARC
DKIM adds an additional layer of email authentication, verifying the integrity of the email's content. Implementing DKIM strengthens your email authentication mechanism and increases the likelihood of passing DMARC policy evaluation.
Step-by-step instructions for enabling DKIM authentication
Enabling DKIM authentication involves generating a DKIM key pair, publishing the public key in the DNS, and adding the DKIM signature to outgoing emails. Follow the instructions provided by your email service provider or consult relevant documentation to set up DKIM authentication correctly.
- Signing: When an email is sent, the sending server generates a unique hash (digital signature) of the email's header and body. This hash is encrypted using the sender's private key and added to the email's header as a DKIM-Signature.
- Publishing Public Key: The sender's domain publishes the corresponding public key in the DNS as a TXT record. This public key is used by the receiver's mail server to verify the signature.
- Verification: When the email is received, the receiver's mail server retrieves the public key from the sender's DNS records. It then uses this key to decrypt the DKIM-Signature and compare it to a newly generated hash of the email. If they match, the email is authenticated as genuine.
Example of Implementing DKIM for a Third Party Tool
Step 1: Generate DKIM Keys
Look into the documentation of your third party tool to find out how to generate and find out DKIM keys. Once you found it:
- Generate Keys:
- Go to the DKIM Core key generator tool.
- Select a key length (2048-bit is recommended).
- Enter a selector (e.g.,
thirdparty).
- Generate the key pair:
- Click "Generate Keys".
- Copy the generated keys:
- Copy the public key provided (it will be used in your DNS settings).
- Copy the private key provided (it will be used in the third-party app).
Step 2: Publish the DKIM Public Key in DNS
- Login to your DNS provider’s management console.
- Add a new TXT record:
- Host/Name:
<selector>._domainkey.example.com(replace<selector>withthirdpartyandexample.comwith your domain). - Type: TXT
- Value: The public key generated from the DKIM key generator tool. It will look something like this:
- Host/Name:
v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQC9sK...
Example DNS TXT Record
thirdparty._domainkey.example.com IN TXT "v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQC9sK..."
