java - grails:无法连接到SMTP主机:*********，端口:25

Question

谁能帮助我，我无法从我的应用发送电子邮件，并且出现以下错误。

日志:

Could not connect to SMTP host: ****.******.** port: 25;

nested exception is:

javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?. Failed messages: javax.mail.MessagingException: Could not connect to SMTP host: smtp.webbfontaine.ci, port: 25;
  nested exception is:

javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?; message exception details (1) are:
Failed message 1:
javax.mail.MessagingException: 
Could not connect to SMTP host: ****.******.**, port: 25;
  nested exception is:

这是我的grails配置:

 grails{
        mail {
            disabled = false
            host = "*****.****.**"
            port = 25
            username = "account"
            password=""
            props = ["mail.smtp.auth":"false",
                     "mail.smtp.socketFactory.port":"25"]
        }
    }

构建COnfig:

compile ":mail:1.0.7"

希望得到您的慷慨帮助。

谢谢

该错误消息还指向SSL连接。似乎您正在尝试使用标准SMTP TCP连接到SSL端口。这是具有类似错误消息的Stack Over流。
