Grails电子邮件插件发送电子邮件失败

Question

我在我的项目中使用了grails电子邮件插件。

最初，我使用gmail帐户配置（官方网站上的文档）来测试，并且我可以成功发送电子邮件。

但是，当我得到客户的电子邮件帐户的详细信息并将其放在那里，它不起作用。

我Grails的配置是：

grails { 
     mail { 
      host = "xxx.xxx.dev.xx" 
      port = 25 
      username = "xx.xx@xx.com" 
      password = "secret" 
      props = ["mail.smtp.auth": "true", 
        "mail.smtp.socketFactory.port": "25", 
        "mail.smtp.socketFactory.class": "javax.net.ssl.SSLSocketFactory", 
        "mail.smtp.socketFactory.fallback": "true"] 
     } 
    } 

抛出的异常是：

难道我在这里错过了什么？

Answer 1

您正在使用SSLSocketFactory，指示SMTP正在运行SSL，但后来您使用端口25指示SMTP未运行SSL。选择一个:)，使用端口465或不使用SSLSocketFactory。

尝试这样的事情对于没有SSL连接：

grails { 
    mail { 
     host = "smtp.example.com" 
     port = 25 
     username = "acount@example.com" 
     password = "password" 
     props = [ "mail.smtp.auth":"true" ] 
    } 
}
