This plugin adds essential email authentication protocols to the default mailer used by many content management systems. It is designed for site administrators who need to ensure their transactional and notification emails are trusted by recipients' servers and avoid spam filters.

DKIM Management: Create, upload, and manage private and public keys for DomainKeys Identified Mail (DKIM) directly from the plugin interface. Configure the selector and domain to cryptographically sign outgoing messages.

SPF Record Tools: Generate a new Sender Policy Framework (SPF) record for your domain, validate existing records, or get recommendations to improve your configuration. This specifies which servers are authorized to send mail for your domain.

DMARC Validation: Check your Domain-based Message Authentication, Reporting & Conformance (DMARC) DNS record settings. The plugin validates your configuration and provides feedback to help enforce your email authentication policies.

Bounce Address Control: Set a dedicated bounce address for failed delivery notifications. Using a domain-aligned address improves sender reputation and reduces the chance of emails being rejected.

Sender Address Configuration: Define the 'From' address and name displayed to recipients, as well as the 'Reply-To' address, ensuring consistency and proper handling of replies.
