SPF如何设置？

eclosion

DNS服务器用的是bind9.3.2
假设域名：test.com

test.com
www.test.com
mail.test.com
smtp.test.com
pop.test.com
以上域名的A记录都指向IP 11.22.33.44

test.com的MX记录指向mail.test.com
IP 11.22.33.44做反向解析到 test.com 和mail.test.com

在BIND的zone文件里面配置了SPF 如下：
IN TXT "v=spf1 ip4:11.22.33.44 ?all"

做了以上工作，但发往MSN 和hotmail的信还是会出现再垃圾邮件夹里，而不是收件箱。

建议从你mail server发封email给sa-test@sendmail.net，然后看看回信，里面包含了domain key, sender ID和spf的测试结果。

Sender ID  和 SPF应该是好的，回信原文如下：

sendmail.net Sender Authentication Auto-Responder $Revision: 1.6 $

This service runs at <sa-test@sendmail.net> and allows remote users
to perform a simple, automated test to see if different Sender
Authentication schemes are working.  Mail sent to this service
is checked by our Sender Authentication filters for any valid
credentials or signatures.  A script receives the message, checks
for a special header with the results of the tests, and composes
this response message based on what it finds.  This response is also
signed with DomainKeys and DomainKeys Identified Mail (DKIM).

Please note that the DKIM filter signing this reply message conforms
to the latest IETF draft version, and thus may not be successfully
verified by older implementations.  If you are using dkim-filter from
Sendmail, Inc., upgrade to at least version 0.4.0 to be compatible
with the most recent version of DKIM.

We hope this service has been helpful to you.
