被spamhaus列入PBL的原因

wakeup1

请问被spamhaus列入PBL的原因除了动态IP和客户端没有开启SMTP身份验证外还有什么可能的原因？

我的邮件服务器被列进PBL了，我想申请解除，但怕没设置好到时又被列进去了，所以想请问一下还有什么原因，谢谢！

另外，我看到spamhaus的FAQ（如下面附上的）里提到要用587端口才是身份验证的，但我imail 9.23版本的也开了验证，客户端也勾选了，结果还是用25端口发送的，请问是什么原因？谢谢！！





Things to check:

• Are your outgoing mail server account, username and password correct? (check them, and remember that passwords are case-sensitive)
• Is the SMTP authentication working correctly at your mail server? (ask your ISP to check)
• Make sure you are connecting to your mail server's 'authenticated mail' port 587 and not the ordinary 'unauthenticated' port 25. (ask your ISP to check for you)
• Mail servers only run spam filters such as Spamhaus PBL on port 25, so if you find you are being blocked by the PBL when you try to send mail to your mail server that means you are not communicating with the mail server on the 'authenticated' port 587 but you're still on port 25. This means your 'SMTP Authentication' is not working correctly. (ask your ISP to check for you)

In summary, if you are being blocked by the PBL when you try to send mail from your PC or Mac to your mail server that means you are sending on port 25, which means that even though you think you have SMTP Authentication switched on, your SMTP Authentication is not working correctly. This can often be something as simple as a bad password, see "Things to check" above.

587是加密端口
