Authentication protocols often do not perform as they should and face technical issues. With our free DKIM Record Lookup and DKIM tester tool, you can instantly view the DKIM record validation status in your DNS in a comprehensive format.
You can easily extract your selector from your email header information. We have covered this topic in detail in our how to find DKIM selector guide.
Your lookup may lead to the discovery of several errors and vulnerabilities in your authentication system, and you need to take steps to resolve them fast before the next attack incident. To troubleshoot:
On generating your record, you’ll be given two keys: one public and one private. The public key will be shared with everyone who sends you emails (or wants to send emails from your domain), while the private key remains secret on your end. These keys are used by your mail server when sending out messages, creating one signature per message so that receivers know where to look for information about its sender.
The specification is defined in RFC 6376.
This in turn verifies the following:
Yes. You can have multiple DKIM records published on your DNS. This facilitates DKIM key rotation for enhanced protection and won’t return an error during your DKIM lookup.
Yes. Your DKIM record does protect you against messager alterations and email spam but it isn’t effective against spoofing attacks without DMARC and SPF. A combination of the three at the right degree of enforcement can be a boon for your email deliverability and your domain’s safety.
