Walkthrough

This change adds conditional SMTP debugging to two files when the application runs in development mode. When _APP_ENV equals development, PHPMailer's SMTPDebug property is set to true in both the mail configuration initialization and the mail worker. This enables verbose SMTP error messages during development for troubleshooting email delivery issues. Existing SMTP configuration and behavior in non-development environments remain unchanged.

351-353: Consider using SMTP::DEBUG_SERVER for more useful debug output.

PHPMailer's SMTPDebug property accepts integer values, not boolean. While true coerces to 1 (DEBUG_CLIENT), this only shows messages sent by the client. For troubleshooting SMTP issues, SMTP::DEBUG_SERVER (2) is more useful as it includes server responses.

+use PHPMailer\PHPMailer\SMTP;

 // ... in the smtp register callback ...
 
     if (System::getEnv('_APP_ENV') === 'development') {
-        $mail->SMTPDebug = true;
+        $mail->SMTPDebug = SMTP::DEBUG_SERVER;
     }

200-202: Same recommendation: use SMTP::DEBUG_SERVER for comprehensive debug output.

For consistency with the suggested change in registers.php and to get more useful debug information (including server responses), use the integer constant instead of boolean.

♻️ Suggested improvement

Add the import at the top of the file:

use PHPMailer\PHPMailer\SMTP;

Then update the condition:

     if (System::getEnv('_APP_ENV') === 'development') {
-        $mail->SMTPDebug = true;
+        $mail->SMTPDebug = SMTP::DEBUG_SERVER;
     }
