我已经能够SPF传递来自Postfix服务器的所有已发送电子邮件.但对于只是将电子邮件重定向到我的gmail ID的转发域,我在SPF中看到了softfail.
例如,如果我从hotmail帐户发送电子邮件至contactus@workingwoman.org,则会转发至测试电子邮件ID ragraggupta8899@gmail.com.
我为我的主机名(host.tariffplans.com)添加了SPF标题“spf1 a mx -all”以及所有域.所有域/子域的A记录正确指向我的服务器IP：23.239.30.81
但在转发的电子邮件标题中.. Google将其显示为softfail.可能是什么问题呢？：

解决方法
您的服务器host.tariffplansindia.com正在接收来自外部的邮件,在本例中为bhasker1@hotmail.com.主持人的接收者是contactus@indianworkingwoman.org.现在,您的服务器将该邮件中继(不更改信封发件人地址)到gmail. gmail服务器现在从您的服务器host.tariffplansindia.com获取一封邮件,信封来自bhasker1@hotmail.com.现在,hotmail.com的SPF-Record禁止除了它自己以外的所有发件人,你不能做任何事情. SPF打破了这种邮件转发,这是一个已知的问题,但它也是由
Sender Rewriting Scheme (SRS)解决的.
使用SRS,中继邮件服务器可以重写信封来自,以便它来自您控制SPF记录的域(host.tariffplansindia.com).不幸的是,在邮件服务器上设置SRS需要 – 在大多数情况下 – 手动编译和安装软件,available implementations的种类非常有限,而且现有的问题是how to perform SRS on postfix.
