DMARC Tag Explanations

TAG	TAG DESCRIPTION
v(required)	The version tag. is the only allowed value is "spf1". If it's incorrect or the tag is missing, the SPF record will be ignored.
IP4	This tag should include all the IPv4 addresses that are allowed to send emails on behalf of the domain.
IP6	This tag should include all the IPv6 addresses that are allowed to send emails on behalf of the domain.
a	The A record tag allows the SPF to validate the sender by domain name's IP address. If left unspecified, it takes the value of the current domain.
MX	The MX record tag checks the MX record of the mail server(s). If left unspecified, it takes the value of the current domain.
ptr (Not recommended)	The PTR tag prompts a PTR check for client IP hostname(s). It's a not recommended tag as per RFC 7208, because it spends too many DNS lookups.
exists	The exists tag checks if an A record exists or not on the mentioned domain.
include	The include tag is of top importance for a correct SPF record. Listing all your sending sources under this tag lets the recipient know that you verify all the aded domains/subdomains as legitimate sources.
all (required)	All is a required tag. It should be placed at the end of the SPF record. Depending on the qualifiers used (~, +, -, ?), this mechanism indicates how the recipient should treat emails from non-authorized sources.
Redirect	The "Redirect" mechanism allows a domain to delegate its SPF authentication to another domain by specifying the redirected domain in the SPF record.

Q. What Is EasyDMARC’s SPF Record Generator?

DMARCtron’s SPF Record Generator enables you to effortlessly create a valid SPF (Sender Policy Framework) record. SPF offers a range of mechanisms, qualifiers, and modifiers, empowering domain administrators to specify authorized IP addresses with precision and flexibility. Designed for simplicity and efficiency, our intuitive wizard streamlines the process, making it quick and straightforward to configure an SPF record tailored to your domain’s needs.

Q. How Is an SPF Record Structured?

An SPF record is structured with a specific syntax that includes tags and values. Its general format is as follows:

v=spf1 [mechanism] [modifier] [all]

Every SPF record must begin with the version identifier v=spf1 and typically concludes with the all mechanism, which serves as the default action for emails that do not match any other defined mechanisms.

An SPF record consists of four key components:

Version Identifier: The v=spf1 tag indicates the version of SPF being used, signaling to the receiving mail server how to interpret the record.
Mechanisms: These define the rules for handling emails sent from specific IP addresses or domains. Mechanisms specify which senders are authorized to send emails on behalf of your domain.
Modifiers: These provide additional instructions for the receiving server, determining how to handle emails originating from IP addresses or domains not explicitly listed in the mechanisms.
All Mechanism: The all mechanism acts as the default policy for emails that do not match any of the specified mechanisms. Common configurations include -all (hard fail) or ~all (soft fail), dictating whether unauthorized emails should be rejected or marked as suspicious.

This structure ensures clarity and precision in email authentication, helping protect your domain from unauthorized use. Tools like DMARCtron simplify the creation and management of SPF records, ensuring compliance and optimal configuration.

Q. How To Generate an SPF Record?

To generate a functioning SPF record, first identify all the sources authorized to send emails on behalf of your domain. These may include your organization’s mail servers, third-party email service providers (ESPs), and other sending sources. Once these sources are defined, incorporate them into your SPF record using the appropriate mechanisms, such as ip4, ip6, and include.

While it is possible to create an SPF record manually if you are familiar with the syntax and rules, using an SPF Record Generator wizard like DMARCtron simplifies the process, ensuring accuracy and minimizing the risk of errors. These tools guide you through the configuration, validate the record, and ensure compliance with SPF standards.

After generating the SPF record, publish it in your domain’s DNS zone by adding it as a TXT record through your domain registrar or DNS hosting provider’s control panel. This step ensures that receiving mail servers can verify the authenticity of emails sent from your domain, improving both security and deliverability.
