The grave significance of SPF for Mail Validation
As an organization that uses emails to connect with customers and promote its products and services, you are in a never ending battle with spam and scams. In fact one of the biggest problems with emails is the ease with which they can be forged these days in the absence of safety protocols. With scammers having gone smarter, traditional email safety protocols aren’t enough to prevent scamming. By implementing SPF record analyzer your organization would be able to protect its domain and prevent its misuse. When implemented together with DKIM authentication and DMARC, an anti-phishing technology, SPF can offer your organization complete peace of mind.
At GoDMARC we are Email experts and have been implementing the latest security protocols for our clients to make their email system safe and protect organizations’ reputation. SPF record checker is one of our most popular offerings and we have implemented this safety protocol for hundreds of clients successfully. Our team stays abreast with the latest security protocols and best practices in implementing SPF lookup protocols allowing us help you use your email as the most potent marketing tool and not fall prey to forgery.
The Sender Policy Framework (SPF) is one of the most widely used email-authentication techniques that helps prevent spamming. With this safety protocol implemented you will be able to prevent spammers from misusing your domain and publish authorized mail servers. With this technology messages from unauthorized IP addresses are marked as suspicious, or rejected depending on the policy that is included in your SPF lookup record
At GoDMARC we implement SPF together with DMARC (Domain-based Message Authentication, Reporting & Conformance) related information and provide the recipient server detailed information on the authenticity of the origin of an email using DNS (Domain Name Service). Once this has been implemented it would give your organization complete control to specify which email servers can send emails from your organization’s domain
We create custom SPF records set by adding unique alphanumeric string before all mechanism that would be used by the recipient server to validate the authenticity of your email. With custom values defined the recipient servers get important information which can be used to verify the source of the email and take necessary steps in terms of sending it to the Inbox of the user.
ISPs have put in strongest security checks to prevent the menace of spam and fake emails. All ISPs these days use email authentication and most of them automatically flag message as SPAM or warn the users when the sender’s credentials cannot be authenticated. Without your emails being authenticated the likelihood of them landing up at the SPAM folder increases which hurts your email marketing campaign. This is where implementing SPF isn’t optional anymore but a must if you wish to maximise the impact of your email marketing campaign.
In the event of SPF record analyser unable to find the sender’s IP address in the SPF record, an SPF failure may occur. In such a scenario the emails can land up in a recipient’s spam folder or be discarded all together. There are two scenarios here – Hard Fail and Soft Fail. Let us now take a look at the two scenarios using examples
Example of SPF Hard Fail:
v=spf1 ip4:192.168.0.1 -all
In the example above the “– (minus sign)” before “all” denotes that emails originating from senders who addresses aren’t listed in the this SPF record would be treated as "hardfail". Hence all emails originating from this source would be treated as unauthorized and discarded immediately. Only the IP address mentioned (192.168.0.1) is authorized to send emails and these would be treated as validated.
Example of SPF Soft Fail:
v=spf1 include:spf.protection.outlook.com ~all
In the above example “~ (tilde sign)” before “all” denotes that servers that are not listed on the SPF record should be considered a "softfail". This would ensure that the mails go through to the recipient but that would be categorized as suspicious or spam. In this example “include:spf.protection.outook.com” would authorize Outlook or Office 365 to send emails. Emails that originate from servers other than mentioned would be categorized as spam.
It is however important to remember that the recipient server isn’t likely to honour the requested behaviour irrespective of the failure mode you specify.
Emails are sacrosanct for modern businesses and any forgery with them can hurt your brand reputation. To ensure your business email is tamper-proof you need to implement SPF without any delay. Get in touch with our team to know more about SPF and how your organization can benefit from it. We shall secure your email system and prevent it from being forged implementing the latest safety protocols.
Sender Policy Framework (SPF), is a protocol which not only allows an organization to authorize hosts and networks to use its domain names when sending an email but also provides a way that a receiving host can check that authorization.
SPF Sender ID is vital for email campaigns. It works as an authenticator that classifies your messages as non-spam. Many popular servers like Hotmail, Yahoo, and Google use SPF as an authenticator. Every business is recommended to use the SPF to make email marketing campaigns safe.
SPF is a beneficial technique to add authentication to your emails. However, it has some limitations which you need to be aware of.
An SPF record has different settings also known as mechanisms. The record is evaluated in order, from left to right. So, if an email host fails to be included according to the first mechanism, it will check the second, third, etc. until it either passes one or fails all checks. If it fails all mechanisms, it will do nothing. This is where it becomes important to include an 'all'mechanism to catch them.
The objective of a SPF record is to determine and stop spammers. Also, it is used to prevent messages with fake ‘From’ addresses on your business domain.
