This plugin configures SMTP (Simple Mail Transfer Protocol) for sending emails from your site, aimed at site administrators and developers who need dependable email functionality. It replaces the default mail system with SMTP, which is more reliable for transactional and notification emails, reducing the risk of emails being marked as spam or not delivered.

SMTP URI configuration: Define your SMTP server settings using a URI format that includes encryption type, username, password, host, and port, supporting options like smtpTLS:// for STARTTLS, smtps:// for SSL, and smtp:// for unencrypted connections.

Error logging: Logs SMTP communication errors to PHP error.log and integrates with security plugins for monitoring, helping you troubleshoot email delivery issues quickly.

Debugging tools: Enable SMTP debugging by adding query strings to the URI, such as ?debug=4, to output detailed communication logs for development and testing purposes.

Automatic Bcc: Add an automatic Bcc recipient by appending a path like /admin_email to the SMTP URI, useful for archiving or monitoring outgoing emails without modifying code.

Configuration flexibility: Set the SMTP URI via the admin interface or define it in wp-config.php as a constant, allowing for easy deployment across different environments and reducing setup time.
