What Is SPF Permerror, And How Can You Combat It?

SPF Permerror is an email validation error that occurs when a domain's SPF record is invalid or malformed. This error occurs when the domain's SPF record contains syntax errors, or if the record is too long. It can also occur when a domain's SPF record contains unauthorized IP addresses or if the record is missing or incomplete. To combat SPF Permerror, you should use an SPF record validation tool to check the syntax of your SPF record and make sure that it meets the standards of RFC 7208. 

Additionally, you should ensure that all IP addresses listed in the record are authorized to send email on behalf of the domain. Finally, you should ensure that the record is updated regularly to be consistent with any changes in the domain's email infrastructure.

What Is SPF Permerror?

A "permerror" is a permanent error in the evaluation of an SPF (Sender Policy Framework) record. This means that there is a problem with the SPF record itself that is preventing it from being evaluated correctly.

There are several reasons why an SPF record might result in a permerror, such as:

When an SPF record results in a permerror, it will typically be ignored by email servers, which means that SPF checks will not be performed on messages that claim to be from the domain in question. This can leave the domain vulnerable to email spoofing, so it's important to address any permerrors as soon as possible.

• Syntax errors in the record, such as missing or extra characters


• Incorrect use of SPF modifiers, such as "redirect" or "exp"


• Use of invalid or unsupported mechanisms, such as "include" or "a"


• Use of invalid IP addresses or domain names

You can use online tools such as "SPF checker" to validate your SPF record and detect if it has any errors. Also, you can check the DNS system of your domain to see if the SPF record is published correctly.

The Most Common SPF Errors - Don't Make These Mistakes

There are several common errors that can occur when creating or implementing an SPF (Sender Policy Framework) record. Here are a few of the most common mistakes to avoid:

• Incorrect syntax: Make sure that your SPF record is formatted correctly and that there are no missing or extra characters. This is the most common SPF error.


• Missing or incorrect IP addresses: Make sure that you list all the IP addresses that are authorized to send email for your domain. Also, double-check that the IP addresses are correct and valid.


• Using too many mechanisms: Be mindful of the maximum number of mechanisms and modifiers that can be used in a single SPF record (10 mechanisms and 7 modifiers are the limits).● Using too many mechanisms: Be aware of the maximum number of mechanisms and modifiers that can be used in a single record. For example, 10 mechanisms and 7 modifiers can be used.


• Not including all sending domains: Make sure that you include all domains that send email on behalf of your organization in the SPF record, such as third-party email services or marketing platforms.


• Not using a valid domain in the "include" mechanism: When using "include" mechanism, make sure that the domain specified is correct and is published with a valid SPF record.


• Using "all" mechanism instead of "-all": If you are using "all" mechanism, make sure to use "~all" or "-all" instead of "all" at the end of the SPF record.

By avoiding these common mistakes and validating your SPF record with online tools, you can ensure your domain is protected from email spoofing and that your SPF is set up correctly.

In conclusion, SPF Permerror is an important issue to be aware of as a sender of emails. It can have a negative impact on your domain reputation and email deliverability. To prevent SPF Permerror, you need to understand the basics of SPF record syntax, make sure all SPF records are valid and up-to-date, and ensure that all IP addresses are included in the records. By following these steps, you can ensure the best possible email deliverability and protect your domain reputation.
