From the developer
Brandon Fowler's own description of Email Auth, lightly tidied.
Email Auth allows you to enable email authentication/validation for your WordPress site. Configure the DKIM selector, SPF, DMARC, bounce address, from address, and reply-to address of emails sent by WordPress through the default PHPMailer.
Configuring these email settings allows you to prevent attackers from spoofing emails from your domain and helps keep your emails out of the spam folder.
DKIM Selector
Create, upload, download, and delete private and public keys for use with DKIM with an intuitive interface. Configure emails to use a DKIM selector and configure which domain should be used with DKIM.
SPF
Create a new SPF record for your envelope domain, validate an existing record, or view recommendations for how to improve your SPF configuration.
DMARC
Validate your DMARC DNS record settings and view comments about your current configuration.
Bounce Address
Set your bounce address to ensure emails are being sent from the right domain to avoid having your emails rejected or marked as spam.
From Address and Reply-To Address
Set the address and name emails are sent from along with the address replies should be sent to.
External Services
This plugin connects to an online list from publicsuffix.org to determine which organizational domain should be searched when obtaining DMARC DNS records. For example, if the domain wordpress.brandonfowler.me does not have a DMARC record, then brandonfowler.me will be checked for a DMARC record. No user information is sent when requesting the list and its usage is subject to the Mozilla Public License Version 2.0.
