大家好!
公司以前一直没有做SPF注册，前段时间因为一封国外的邮件因为SPF退信了，所以去域名托管中心做了一个TXT记录：v=spf1 ip4:202.173.234.160/28 -all，可是好象也不对。因为最近发126、163的邮件也会被退回来。
现在我把公司的环境发过来，请高人指点。
公司邮件
服务器是EXCHANGE
2007，
有两个接收连接器：enten.com
yongxin-enten.com
但是发出去的邮件，返回来的错误报告显示为：内部网络的计算机名，
server.enten.com,而非外部网络的域名mail.yongxin-eten.com
就算去服务器把enten.com禁用也是一样。
然而，通过Telnet 上去，返回来的，却显示是域名mail.yongxin-enten.com
去SPF官网，进行测试，返回测试报告为：
