      • 看起来好像是发送方mta被hotmail block的问题
      • IP段被outlook封了?是有人和你用同样的host服务然后发垃圾邮件太凶了?
        • Rolia is using a dedicated server. No others would be able to send through the same host.
          • 你的server地址对吗?另外,真正传出邮件的server未必是你的。
            • I have no idea. The point is, among many many different email recipients, only using hotmail.com get the problem.
              • 楼下说的对,hotmail多事
          • 我是说用同样的host服务商,然后导致IP段被封。Rolia是躺枪的。
            • 这样做,hotmail是在自杀。
              • 可以考虑联系你的service provider,要求他们解决这个问题。
                • Thanks. I did.
          • 如果你是刚换server,这个IP以前发spam,被列到黑名单里了。hotmail会给你一个link,填表后能找到管理员,但处理要一段时间。
            • I did that a few years ago. There was no response though.
      • 系统,请问怎么 PM 你? +1
        曾经遇到过的一种情况是:用户使用了第三方公司的 filter service。domain 可能缺省被设置在 blacklist上,可以尝试发个delist request。第三方公司处理后,就可以remove from blacklist了。上次遇到的提供 filter service的第三方公司是https://www.invaluement.com/。但不知道 hotmail 之类的是不是也是这种情况以及也使用这家公司的服务。
        • Thanks for the information! Please email to rolia@rolia.com. The system account doesn't use PM.
          • 还有,关于email tagged malicious,从而被 block 的问题,说是 domain 加上 DKIM 和 SPF,也可以使 emails should no longer go to spam. +1
            • Thanks again!
