This plugin configures a site's email system to use an SMTP server for sending messages, ensuring emails are delivered reliably instead of being blocked or marked as spam. It is designed for site administrators who need to improve email deliverability from their platform.

SMTP Server Configuration: Set up your outgoing mail server details, including server name, port, and encryption type (e.g., SSL or TLS). Authentication Settings: Provide a username and password to authenticate with your mail server, securing email transmission. Sender Customization: Define default 'from' name and email address, with an option to override other scripts for consistency. Debugging and Testing: Enable logging for wp_mail and phpmailer to troubleshoot issues, and send a test email to confirm the configuration works. Custom Headers and Filters: Add custom headers to all outgoing emails and use filters to programmatically adjust sender details as needed.
