我正在尝试在 grails 中配置 zoho 邮件服务 mail-plugin .到目前为止，这是我的配置，

    grails {
    mail {
        host = "smtp.zoho.com"
        port = 465
        username = "email@valid.com"
        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"]
    }
}

这是我的服务方式。如果我把 gmail smtp 配置放在上面，上面的配置效果很好，所以我认为服务方法完全没有问题。 email@valid.com 也是 Zoho 中的注册邮箱，我可以使用 zoho dashboard 发送邮件。

    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)
            }
        }

这是堆栈跟踪，

最佳答案

您只需在添加电子邮件逻辑的地方提及“setFrom()”属性。 示例:我使用 JavaMailSender 并使用 MimeMessage 发送电子邮件，因此在这种情况下，我将不得不提及“helper.setFrom()”。

P.S: 我试了很多方法，然后用这个解决了。
