SINA邮件系统有垃圾邮件保护系统，必需能回访到你发信的IP地址和域名

U-Mail

Socket 连接建立(192.168.2.18 : 3555 -> 202.106.182.230 : 25)<br>
<br>
<br>
这里就不行

那这个问题怎么解决呢<br>
我的MDaemon也这样， 还不能往hotmail发送邮件<br>
情况和上面的一样<br>
请问斑竹什么方法能解决呀？<br>
多谢！

U-Mail

做邮件服务器必须要有合法的IP

我申请了电信光纤专线接入，有合法的IP,请问版主为何不行?

ldyworld

你的邮件太大了，你邮件的大小是附件乘以137％

我的邮件服务器也有类似问题。<br>
最近有时是发不行，有时是收不到。往sina.163.sohu等都有。<br>
我都快被疯了！！！<br>
