(grails) com.sun.mail.smtp.SMTPSendFailedException: 553 Ретрансляция запрещена как zoho mail

Я пытаюсь настроить почтовый сервис zoho в плагине почты grails. Вот моя конфигурация на данный момент,

    grails {
    mail {
        host = "smtp.zoho.com"
        port = 465
        username = "[email protected]"
        password = "some-valid-password"
        props = ["mail.smtp.auth":"true",
                 "mail.smtp.starttls.enable":"true",
                 "mail.smtp.socketFactory.port":"465",
                 "mail.smtp.socketFactory.class":"javax.net.ssl.SSLSocketFactory",
                 "mail.smtp.socketFactory.fallback":"false"]
    }
}

Вот мой метод обслуживания. Вышеупомянутая конфигурация отлично работает, если я поставлю конфигурацию smtp gmail, поэтому я думаю, что проблем с методом обслуживания вообще нет. Также [email protected] - это зарегистрированный адрес электронной почты в Zoho, и я могу отправлять электронные письма с помощью панели инструментов zoho.

    def sendImageProcessedNotification(User user, imageLink){
            try{
                if(user){
                    def receiver = user.email
                    mailService.sendMail {
                        async true
                        to receiver
                        subject "Subject"
                        html "Html body"
                    }
                }
            }catch(e){
                log.error(e)
            }
        }

А вот трассировка стека,
