What is SPF Record Check?

In recent years, it has become important to obtain security conditions in the e-mail addresses used in connection with these domain names, together with the registration of domain names and the secure use of domain names. Accordingly, one of the most important standards within the scope of the "E-Mail Sender Policy" standards created in the past years is the SPF record. The SPF record is used to verify that the sending address is real and secure in emails sent from any server. In this context, when an e-mail sent to the receiving e-mail server is delivered thanks to the SPF record query process, a query is performed to determine from which server this e-mail was sent.
What is SPF Inquiry?

Why is SPF Record Necessary?

SPF records are an absolute necessity for e-mails to be used in a domain name together with this domain name. Because with this record, it can be confirmed that the e-mails are coming from the right place. In addition, while it is possible to prevent fake, that is, spoof e-mails, it is also possible to prevent phishing traps. A clear SPF record is always important for verifying the email sender, preventing email spoofing, preventing spam, as well as forwarding emails from your domain in a secure location to the recipient.

How SPF Records Work

While the SPF records are stored on the DNS server, when a mail arrives from the sending mail server to the receiving mail server, the receiving server performs an SPF record query on the server. As a result of this query, when an SPF feedback is received from the sending server, the result is obtained with the control. If the SPF record obtained as a result of the check is in a valid point, the e-mail is considered reliable and accepted by the receiving server. If the query result does not contain a reliable SPF record, this email is treated as spam and will not be accepted. That is, the receiving server performs an SPF record query for the email sending domain to determine whether the incoming email is from an authoritative or unauthorized server.

Frequently Asked Questions

The SPF record is basically useful for confirming the server that the e-mail is coming from, determining that it is not fake, and also preventing harmful e-mails.

Although there is more than one method for this, you can use our SPF inquiry page offered to you by Atak Domain as the first method. As another method, when you type the CMD command after entering the run application in the start menu on your own computer's terminal screen, you can perform SPF querying through the houses that appear.

SPF records contain a version number for each record. This version number starts with the characters "v = spf1". Starting with this version, there are unlimited registrations from start to finish.
In fact, although these records are directives, these so-called directives are usually mechanisms that define the authority of the post, sometimes hitting a qualifying and clear IP address in the optional location, or sometimes no hits. Accordingly, the first mechanism that shows a hit clearly reveals the evaluation result of the desired SPF record.

The evaluation result in SPF records depends on certain rules. Within the framework of these rules;
• When the Q-Syntax position is (+), the “Pass” result code is obtained and the authorized sending server is defined and a positive result is obtained as standard.
• Although the result is "Fail" in the (-) position, the IP is not authorized and if there is an e-mail from the source, it is sent back incorrectly.
• In the case of (~) position, while the result code is evaluated as “SoftFail”, servers may be defined for unauthorized e-mail. But this error is handled deliberately.
• Finally, the “Neutral” result appears with the (?) Q-Syntax position. In this case, since the e-mail server that sent the e-mail clearly defines the legitimacy of the rules, this e-mail will be accepted.

There are common operating mechanisms that are clearly seen in SPF records. Among these mechanisms, depending on the state of the instruction;
• In the All mechanism, the instruction is always valid.
• In the query performed with the domain name in the MX mechanism, the MX record and the MX IP address are included.
• In the IPv4 mechanism, the sender's IP address or the specified IPv4 subnet contains the IPv4 address specified in the query.
• In the IPv6 mechanism, the IP address of the sending server or the specified IPv6 subnet is considered the IPv6 address specified in the query.
• The MX record of the domain name and the MX IP address is included in the content, together with the query made in the A mechanism.
• For the domain name specified in the Include mechanism, an additional separate SPF request is requested to include the sender's IP address.
• Another domain name's SPF record in the redirect mechanism also legitimizes the sender's IP address.
• In the Exists mechanism, the IP address of the sender is authorized in the context of a client connection or different criteria within the framework of RFC7208.

At Atak Domain, our technical personnel will assist you in creating, querying, and processing SPF records every day, thanks to uninterrupted expert support for you.
