群晖邮件服务只能收，不能发，求助配置要点

p2dgep0f · 发表于 2016-3-29 20:40:19

根据说明配置好相关用户和打开各种服务，端口已经都映射了，ddns也已经有了，外网能正常打开各种服务，但是只能收到邮件，不能发送，错误提示如下，难道是被邮箱供应商屏蔽？另外请教各位一般都用的什么付费的域名服务啊

没办法，现在大的邮件服务商都有邮件过滤功能，不在他们白名单上的邮箱服务器基本上都会被屏蔽

我也搭了群晖mailserver，用的dnspod申请的CC域名，发邮件的话，貌似只有admin用户能发送成功。到qq和163这些收发都是正常的。

应该是被过滤了，你发到免费邮箱看看，可能能行。按理是发送邮件的配置比接收简单。

邮件服务器的域名最基本的你要做 MX记录。然后对于绝大多数邮件服务器商，你还要给你的邮件服务器域名做SPF记录和域名的反向记录。而最讨厌的就是这个域名的反向记录，就算你有自己的DNS服务器，自己做是无效的，必须是你这个IP所属的ISP供应商来做。

否则基本上你这个邮件服务器的邮件发出去的邮件都是被退回的。

我用的是3322的付费域名，里面好像没有mx记录和反向记录的设定，真是啃爹啊

我也只做了A记录而已，不知为何能成功。
不过只有admin用户可以成功发送，其他用户都会550 Mail content denied 被退件。
