Released in 2003, the OpenSPF.org website quickly became a popular starting point for developers and mail server administrators implementing SPF rules. SPF stands for Sender Policy Framework, and it’s a widely used tool to fight spam. The site also served as a resource for those interested in getting involved in the community of SPF developers and maintainers.

Unfortunately, OpenSPF.org disappeared from the internet in February 2019. We have prepared an OpenSPF.org introduction that will teach you more about the origins and purpose of the tool. Also, we took some time to try to understand what happened to the website. We also attempt to identify some resources that are still available to fill the void left by OpenSPF.org’s demise.

Origins of OpenSPF.org

OpenSPF.org provided information about SPF and its benefits, along with news, tools for configuring SPF, forums, and FAQs.

SPF is a method of informing servers whether a specific mail server is authorized to send an email from a particular domain. Hence, it can detect whether an email address is authentic or fake before allowing it to pass into an inbox.

An SPF record increases the likelihood that emails sent by valid addresses are delivered. Without it, your email could be categorized as spam. It also protects against malicious emails sent through your domain by spammers.

Meng Weng Wong is widely credited as the creator of SPF. However, he culled inspiration from various sources. Paul Vixie’s paper Repudiating Mail-From led to two proposals: Reverse MX by Hadmut Danisch and Designated Mailer Protocol by Gordon Feyck. Wong combined these proposals to create OpenSPF in 2003. The volunteer groups involved in the SPF project included the SPF council, a support team, webmasters, and mailing list moderators.

What Happened to OpenSPF.org?

OpenSPF simply disappeared from the internet. There was never an official announcement of its closure, and the last archive of the site is from February 2019. In April 2019, users of the online platform Reddit were still trying to find out what happened to the site. Some users attributed the demise of the site to a lack of funds.

While OpenSPF.org may no longer be available, several websites and tools are still useful for those writing and testing SPF rules for their mail servers. 

OpenSPF.org Tools

These sites provide tools similar to those of OpenSPF.org.

Kitterman Technical Services

This website offers tools for setting up an SPF record. Kitterman’s tools are unique and employ Python software known as pyspf. One of the available tests assesses whether your SPF record is valid. Another test checks the performance of your SPF record based on the IP addresses from which the emails come.

Appmaildev.com

Appmaildev.com is another site that allows users to test their SPF records. You are given a test email address to which you can send an email. After that, an SPF report is generated. Appmaildev.com also has tutorials available for adding signatures and stopping spam emails. For less-advanced users, SPF-related topics can be tricky, making this a handy tool.

MX Toolbox

MX Toolbox allows users to look up their SPF records. With this website, users can publish a list of domains that are authorized to send an email on their behalf. This list ensures that malicious mail senders have nowhere to hide, thereby reducing spam in the process. You can also check whether your email server has been blacklisted through blacklist check.

Bevhost.com

Beveridge Hosting DNS Lookup is a tool made available by the web hosting company bevhost.com. It provides you with a form where you can simply enter a hostname or IP address. The site will then verify whether the hostname or IP address is authentic.

What is SPF email authentication?

SPF stands for Sender Policy Framework. It is an email validation method designed to detect forged sender addresses while the delivery of an email takes place. It is important to point out that SPF alone is limited to detecting a forged sender claimed in the envelope of the email, which is used when the mail gets bounced.

Does SPF prevent spoofing?

SPF is an email authentication system designed to block spam by detecting email spoofing. Therefore, an SPF record can reduce the likelihood of your domain name getting fraudulently spoofed. Also, it can keep your messages from getting flagged as spam before they reach your recipients.
