Do you want to check the SPF record of your domain and check whether a valid and substantial SPF record exists?
Well, our online SPF record checker is the best solution and answer to your question.
The best SPF record checkers are online SPF demonstrative tools that show a graphical view of SPF records. The graphical view permits individuals to recognize authorized servers quickly and to send forward on behalf of a website/domain. (Note that this demonstrative instrument centers on domain-level verification and overlooks the parcels of SPF that influence the neighborhood parts of mail addresses.)
There are various SPF record checkers like DuoCircle SPF record check, Kitterman SPF checker, Mxtoolbox SPF checker, and Fraudmarc SPF checker.
DMARC Analyzer is the pioneer of DMARC, provides a user-friendly analyzing software, and acts as an expert guide into moving organizations towards building a reject policy and act as fast as possible. Organizations use DMARC analyzers to protect their brands against abuse in phishing or spoofing attacks.
The SPF Record lookup Will Validate SPF Records On:
check SPF record existence
Logically, to check SPF record existence, we require an SPF record in your DNS so we can validate the record.
Various SPF records in DNS
There is only one SPF record in DNS for each SPF version. So, if you have one SPF record in DNS, then there would be one SPF version for each. Therefore, if you publish several SPF records (v=spf1), it will invalidate your SPF record. So, always update your SPF record rather than entering a record alongside the previous and existing one.
Maximum DNS Lookups
When using SPF, you can only perform 10 DNS lookups for valid SPF record check
PTR Mechanism
It is recommended not to use PTR as this is a detested mechanism, and if you use this mechanism, many senders may ignore your SPF record.
The function of a PTR record and of an A record is totally opposite. The PTR record resolves an IP address to a domain name, instead of a domain name to an IP address. The PTR mechanism substantiates only if the DNS reverse-mapping for an <ip> exists and can point to a domain name within a specific domain.
The PTR mechanism is slow and comparatively unreliable as compared to other mechanisms in case of DNS errors therefore does not use the PTR mechanism.
Unknown Parts Found
We have detected content that is not in the SPF requirements.
+All Mechanism Used
The use of the mechanism ‘all’ with a “+” qualifier means you basically allow anybody to send an email on your behalf. Firstly, the record will try to match the sending source to another mechanism. But if the first action fails, the default behavior is to still allow this source. Therefore, this setup is not recommended.
Invalid Macro
Our SPF record checker will try to substantiate and validate the SPF macro’s you are using. After analyzing some exemplary data, we will give examples of the lookup receivers based on your macro setup.
Record Termination Missing
You must be aware of the fact that an SPF record should have a ‘default’ fall-back mechanism. This can either be an ‘all’ mechanism or a ‘redirect’ modifier. Further, we will check with either of these until you end your SPF record.
Different Fall back Scenarios
An SPF record always should have one fall-back scenario. Therefore, avoid multiple fallback scenarios.
DNS Type “SPF” Used
You have published your SPF record in a DNS type SPF. The DNS type ‘SPF’ was introduced in RFC 4408 in 2006. However, this type became outdated following RFC 7208 which states: SPF records have to be published as a DNS TXT (type 16) Resource Record (RR).
Uppercase SPF
We always recommend it to use the best practice to publish your SPF records in lowercase. Because the Uppercase character in the SPF records is not a requirement.
After running your SPF record through all the above-mentioned checks, you can safely update your SPF record in your DNS.
