用Jmail做过邮件发送程序的帮下忙,奇怪的问题.在线等了

Question

在做一个邮件发送程序的时候,用我自己的邮箱做([email protected]),成功了,可以正常发送邮件.然后从新申请了一个邮箱([email protected])去测试却不成功了,确保密码是对的,可以尝试(buy820704),都是163的,为什么一个可以,一个不可以啊.高手指导,在线等了

Answer 1

部分代码如下:
          string FromEmail = "[email protected]";//这里用[email protected]却能成功.
          string mailServerPassWord = "buy820704";
            string mailServer = "smtp.163.com";

Answer 2

都验证过了,用我的第一个邮箱也可以.但后来申请的就不行了.是不是smtp.163.com这个改变了啊?

Answer 3

唯一能怀疑的我觉得就是smtp.163.com改变了

Answer 4

我用另外一个新浪的邮箱测试了,也成功了.smtp.sina.com.cn
真估计是不是后来申请的邮箱他的服务器不是smtp.163.com了

Answer 5

没有强人来的话就只有关注了.我是想不出还可能什么原因了.SINA的也是,我刚申请的邮箱也通不过测试,是不是只有用老邮箱啊。现在新注册的邮箱都不能用.有点荒唐,但没法解释了

我之前也用163申请了一个，用FoxMail发不了邮件，但后来好像升级到3G吧，就可以了。
