说的很对啊,但如果那样设置还会有退信呢!作者: dennishan 时间: 2008-11-18 21:46
楼主根本混淆了Icewarp的SPF作用,SPF记录和邮件系统无关!在域名解析里面设置就OK了!
发不出去邮件和SPF也没太大关系。根本就是IP信誉度问题。作者: tdk 时间: 2008-11-18 22:16 标题: 回复 3楼 dennishan 的帖子 lz每次出来都会满腔热情地搞点事故作者: kenny61736 时间: 2008-11-18 23:56
SPF technology allows the domain owner to add an additional DNS record for the domain, specifying which machines are authorized to send messages that report to be from this domain. Any SMTP server that is SPF compliant can check these records against the actual sending machine and decide whether to allow the message through.
But an inherent problem of SPF is SMTP forwarding . When a server forwards a message without changing the "mail from" Header this new message could fail SPF checking. This is solved by implementing SRS (Sender Rewriting Scheme ). SRS forces the rewriting of the " mail from" address by the forwarding server.
