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

构建COnfig：

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

希望得到你的慷慨帮助。

Answer 1

错误消息还指向SSL连接。好像您正在尝试使用标准SMTP TCP连接到SSL端口。这是一个Stack Over流，它有一个类似的错误信息。

unrecognized ssl message plaintext connection exception

Answer 2

确保使用正确的SSL端口号。默认情况下，SSL / TLS加密的SMTP使用端口465.

grails：无法连接到SMTP主机：*********，port：25
