How to verify email authentication?

Mail has always been the main instrument used in cybercrime. Hackers imitate and hijack other people’s domain names. That is, they create emails from your domain. To address this, mail providers are deploying more sophisticated methods and technologies to manage mail flow. Email authentication is the most basic protection. Consider email authentication as a hard-to-spoof digital signature for your domain, protecting your brand, identity, content, and reputation. To implement email authentication, you must configure your domain’s DNS records to include extra information in the email headers. You may then verify that it originated from an approved mail server or IP address linked with your domain. While this verification is optional, it increases the chances of your letter reaching your recipient which are SPF, DKIM, and DMARC.

SPF stands for Sender Policy Framework and describes a mechanism to check an email message delivered from an authorized mail server to identify forgery and spam. SPF standards allow domain owners to identify which mail servers they can transmit from.

DomainKeys Identified Mail (DKIM)

DKIM is a method of email authentication that allows an entity to claim authorship for a communication. DKIM employs “public key cryptography” to authenticate an email message was delivered from an authorized mail server, preventing forgery and spam delivery.

Domain-Based Message Authentication Reporting and Conformance (DMARC)

For improved domain protection from fraudulent email, DMARC employs SPF and DKIM to provide linkage to the author (“From:”) domain name, written standards for recipient handling of authentication failures, and reporting from receivers to senders.

WordPress Email Optimization

If you’ve done all the testing, but still does not fix the problem then it’s probably a plugin issue. Each WordPress plugin is unique, and if you use numerous plugins, they must all operate well together, but this is not always the case. Plugin updates may cause conflicts with other plugins. So knowing your plugins and how to configure them is crucial. Some troubles with email plugins are due to configuration errors. Clients may identify emails as suspicious or spoofing if not set properly (e.g. Contact form plugins frequently rewrite the From: field’s address or change other information that may be suspicious.)
