谢谢上面这位仁兄的建议,现在防垃圾邮件功能太强大了,发送失败后,连上sina得到以下的提示。如果你是从163向sina发,sina的smtp会检测你发邮件 的ip地址,与163的IP地址匹配。不一致,它就拒绝了。
Why did SPF cause my mail to be rejected?
What is SPF?
SPF is an extension to Internet e-mail. It prevents unauthorized people from forging your e-mail address (see the introduction). But for it to work, your or your e-mail service provider's setup may need to be adjusted. Otherwise, the system may mistake you for an unauthorized sender.
Note that there is no central institution that enforces SPF. If a message of yours gets blocked due to SPF, this is because (1) your domain has declared an SPF policy that forbids you to send through the mail server through which you sent the message, and (2) the recipient's mail server detected this and blocked the message.
sina.com rejected a message that claimed an envelope sender address of akingfly@163.com.
sina.com received a message from 211.143.246.37 that claimed an envelope sender address of akingfly@163.com.
However, the domain 163.com has declared using SPF that it does not send mail through 211.143.246.37. That is why the message was rejected. |
