我按你的操作新增了那两个邮箱用户，但现在还是无法发送，详细信息参考附件截图

我现在是自己发给自己都报这个错误，外部的更不行，我不知道为什么会发生这样的错误，难道这么多人都没遇到这种情况，要找到根源才能彻底解决，我想应该还是在服务端入手，但不知道如何做（是否跟iredmail版本有关系，我的版本是0.9.2）

iRedMail 默认没有启用任何 RBL 服务，主要是因为偶尔有些正常的邮件服务器会被误杀，会造成一定的麻烦。所以交给系统管理员自行决定是否添加、以及添加哪些 RBL 服务。

看你添加了那么多，不确定你是否真的明白这几个 RBL 服务的可靠性，也许只是从网上的文章里抄来的？

这个配置文件在哪里设置，如何取消这个服务？？？

我把红色字体删除后能接收邮件，但发邮件对方都收不到（发送提示成功）

我把红色字体删除后能接收邮件，但发邮件对方都收不到（发送提示成功），是不是有哪些不能删除的？

能否提供一个正确mian.cf配置文件给我参考？
