How To Fix An SPF Permerror So Your SMTP Is Secure
In today's world, email has become an essential part of communication. We rely on it for everything, from business to personal correspondence. As such, it's important to ensure that our emails are secure and can be trusted. One way to do this is by setting up SPF records for our domains.
SPF (Sender Policy Framework) is a type of DNS record that helps to prevent email spoofing, phishing, and other types of email fraud. However, sometimes we might encounter an SPF Permerror, which can prevent emails from being delivered. This can be frustrating, but it's not something that can't be fixed.
In this blog post, we'll explore what an SPF Permerror is, why it happens, and how to fix it. We'll also discuss the importance of having a secure SMTP (Simple Mail Transfer Protocol) and how it relates to SPF records. duocircle.com has great information on SPF permerror.

What Is An SPF Permerror ?
SPF (Sender Policy Framework) is an email authentication method that allows email recipients to verify that incoming messages are actually sent from an authorized server. When an email server receives a message, it may check the SPF record of the sender's domain to determine whether the message is coming from an authorized server.
An SPF Permerror (permanent error) is an error that occurs when an SPF record is improperly configured, preventing the email server from properly checking the SPF record. This can happen for a number of reasons, such as syntax errors in the SPF record, exceeding the DNS lookup limit, or a DNS server being unreachable.
When an SPF Permerror occurs, the email server cannot determine whether the sender is authorized to send emails from the specified domain, so it may choose to mark the message as spam or reject it outright. It is important for domain owners to ensure that their SPF records are properly configured to prevent Permerror and ensure successful email delivery.
How To Fix An SPF Permerror?
Fixing an SPF Permerror can be a bit technical, but it generally involves making sure that the SPF record is properly formatted and contains accurate information. Here are some steps you can take to fix an SPF Permerror:
- Check your SPF record syntax: Make sure that the syntax of your SPF record is correct. The SPF record should start with "v=spf1" and end with "-all". It should contain all authorized servers that are allowed to send email on behalf of your domain.
- Check your DNS settings: Make sure that your DNS settings are properly configured to allow SPF records to be looked up. Ensure that the SPF record is published in the DNS zone file for your domain.
- Avoid DNS lookup limits: If your SPF record includes a large number of authorized servers, it may exceed the maximum number of DNS lookups allowed by the recipient's email server. To avoid this, you can use mechanisms like "include" to consolidate multiple SPF records into a single record, or use "a" or "mx" mechanisms to include all servers associated with a specific domain.
- Test your SPF record: Use an online SPF record checking tool to verify that your SPF record is properly configured and not resulting in Permerror. You can also use email testing tools to check whether your SPF record is working as expected.
- Monitor your email delivery: After making changes to your SPF record, monitor your email delivery to make sure that your messages are being properly authenticated and delivered to recipients.
In conclusion, fixing an SPF permerror may seem daunting at first, but it is an important step in securing your SMTP server. By carefully reviewing your SPF record and making any necessary changes, you can ensure that your emails are delivered safely and reliably. It is also important to regularly monitor and update your SPF record to ensure that it remains up-to-date and effective. By following these steps, you can help protect your organization's email communications and maintain the trust of your customers and partners.
