![postfix & cyrus-SASL SASLDB2 0: NO“身份验证失败”](https://linux22.com/image/103008/postfix%20%26%20cyrus-SASL%20SASLDB2%200%3A%20NO%E2%80%9C%E8%BA%AB%E4%BB%BD%E9%AA%8C%E8%AF%81%E5%A4%B1%E8%B4%A5%E2%80%9D.png)
我们正在设置 Postfix 邮件中继,以仅接受经过身份验证的 smtp 会话并将它们转发到我们的后端智能主机。
CentOS 6.8
postfix-2.6.6-6.el6_7.1.x86_64
cyrus-sasl-lib-2.1.23-15.el6_6.2.x86_64
cyrus-sasl-md5-2.1.23-15.el6_6.2.x86_64
cyrus -sasl-2.1.23-15.el6_6.2.x86_64
赛勒斯-sasl-plain-2.1.23-15.el6_6.2.x86_64
我们已经根据 postfix.org 上的 postfix 手册中的一些教程和参考资料安装和配置了 Postfix 以及 SASL,尽管我们似乎有一些配置或权限错误。任何帮助,将不胜感激。

如果更多日志或配置摘录有帮助,请告诉我。提前致谢
答案1
我在 exim 上也遇到了同样的问题。
您可以使用 cyrus 在服务器 shell 上测试用户名和密码,例如
testsaslauthd -u username -r example.com -p secret
它不适用于
testsaslauthd -u [email protected] -p secret
我的帖子有进一步的解释:Cyrus sasl 错误 - ''0:没有身份验证失败”在 Debian 9 上
答案2
您是否为中继主机设置了 /etc/postfix/sasl_passwd 通常需要中继邮件。另外 mydestination 尝试将其仅设置为 localhost,看看会发生什么。我希望这有帮助
