特别是发到国外的，下面是系统退信：

是不是我们这里的电脑中毒，对

退信提示对方没有改用户名，系统产生退信！

楼主，正常的退信，对方服务器返回信息：Diagnostic-Code: smtp; 550 "pascalciteau@marinelec.com" is not a known user

没有这个用户，你看一下是否你写地址了，核实一下再次发送。

备注；一般550或5开关的退信，都是永久性的错误，

我用的是126的免费邮箱，想发邮件给一些企业邮箱如jh@sh-jinhong.cn为什么发不出去呢，该怎么办呀？为什么gmail.cn发不出去邮件？ 21cn企业邮箱的优势在哪里? 为什么短信息内容为“食人妖回族”发不出去！邮件发不出去短信发不出去！！！电子邮件发不出去手机短信发不出去手机短信发不出去 ? outlook发不出去
