Bug: SMTPDebug pollutes AJAX queries

    Hi,

    Postman/Phpmailer/PostsmtpMailer.php::phpmailer_smtp_init() turns on full debugging for the SMTP class by setting $mail->SMTPDebug = 3;, (a value of SMTP::DEBUG_CONNECTION).

    As a result, SMTP pollutes AJAX calls if an email is sent during the call – which in turn breaks front end functionalities.

    In our case, we found that buddypress messaging had become unresponsive. i.e The user hits send and nothing appears to happen, because bp receives a garbled json response containing the SMTP log.

    Please fix,

    Thanks,

    J
