What is SPF Record and how to query it?
Prefent email spoofing
SPF or Email Sender Policy Framework aims to prevent the spoofing of sender addresses in emails. In particular, emails should be prevented from being sent via unauthorized mail servers.
For this purpose, additional information is stored in the DNS (Domain Name System) in the form of an SPF record. This TXT-based SPF entry contains certain information about authoritative mail servers.
The receiving mail server can query the SPF record of the sending domain to check whether the received email comes from an authorized mail server or an unauthorized server. In the latter case, the email can be identified using SPF spam protection and declared as spam.

SPF Checker
SPF Checker is a tool that verifies whether a domain's SPF (Sender Policy Framework) record is correctly configured to prevent email spoofing.
SPF Record Creator
SPF Record Creator is a tool that helps generate the correct SPF record for a domain to authorize specific mail servers to send emails on its behalf.
Mx Record Checker
MX Record Checker is a tool that verifies and retrieves the Mail Exchange (MX) records of a domain to ensure proper email delivery setup.
DKIM Record Checker
DKIM Record Checker is a tool that validates the presence and correctness of a domain's DKIM (DomainKeys Identified Mail) record to ensure email authentication and integrity.
DMARC Record Checker
This is a tool that verifies the existence and validity of a domain's DMARC (Domain-based Message Authentication, Reporting, and Conformance) record to ensure email authentication and policy enforcement.
Whois Domain Checker
Whois Domain Checker is a tool that retrieves detailed information about a domain's ownership, registration, and expiration status by querying the Whois database.
NS Checker
NS Checker is a tool that verifies the nameserver (NS) records for a domain to ensure proper DNS configuration and resolution.
Mail Blacklist Checker
Mail Blacklist Checker is a tool that checks if an IP address or domain is listed on any email blacklists, which can affect email deliverability and reputation.

Each SPF record begins with a version number; "v=spf1" represents the current SPF version.
An unlimited number of records follow, which are evaluated sequentially from beginning to end. Most of the records are pseudo-directives that define the sender's authorization and consist of an optional qualifier and a pseudo-mechanism that results in a hit or no hit for a given state (IP address). The first mechanism that represents a hit determines the outcome of the entire evaluation of the SPF record.
The following rules determine the outcome of the entire evaluation of the SPF record.
| Q-Syntax | Result code | Explanation |
|---|---|---|
| + | Pass | Authorized sending servers are defined; this is standard, so if no qualifier is specified, + is assumed. |
| - | Perpetrator | If an e-mail is sent from an unauthorized IP or source, the relevant error is returned. |
| ~ | SoftFail | Unauthorized sending servers may be defined. However, the recipient must handle this error consciously. |
| ? | Neutral | The sending server identifies channels whose legitimacy nothing should be said about them, and thus the mail is accepted. |
In the table below you can see some common operating mechanisms.
| Mechanism | Valid states of the given instruction. |
|---|---|
| All | Always |
| A | Contains the MX record or MX IP address of the queried (or explicitly specified) domain. |
| mx | Contains the MX record or MX IP address of the queried (or explicitly specified) domain. |
| ip4 | The specified IPv4 address is the sender's IP address or the specified IPv4 subnet contains it. |
| ip6 | The specified IPv6 address is the sender's IP address or the specified IPv6 subnet contains it. |
| redirect | The sender's IP address is legitimized by another domain's SPF record |
| include | An additional SPF request for the domain specified in the include statement includes the sender's IP address |
| exists | Authorized based on the sender's IP address, client's connection, or other criteria as per (RFC7208). See: (RFC7208) |
