同时给gmail邮件id和gmail smtp它的工作但是当使用rediffmail和smtp时它获取的信息就像服务器没有支持安全连接。

推荐答案

尝试将端口号更改为25而不是587。 587用于gmail帐户，rediffmail用于25.另外，检查smtpobj.UseDefaultCredentials值，如果是安全连接，则需要将其设置为false并提供与该帐户关联的用户名和密码。

希望这有帮助......

Try changing the port number to 25 instead of 587 . 587 is for gmail account and rediffmail uses 25. Also , check the smtpobj.UseDefaultCredentials value, if its secure connection then you need to set it false and provide username and password associated with the account.
