我正在运行rhel 7.2，我已postfix安装但无法通过 gmail smtp 服务器进行中继。我已遵循许多教程并在 Google 上搜索并尝试回答许多其他帖子，但似乎无法让任何事情正常工作。
这是我当前遇到的错误/var/log/maillog（为了保护隐私，我将主机名和电子邮件地址替换为 x：

我尝试了网上的多种解决方案，我的/etc/postfix/main.cf文件最终如下所示：

顺便说一下是该文件postfix的所有者/etc/postfix/sasl/passwd
如果有人有任何建议我将不胜感激！！！
答案1
检查格式是否/etc/postfix/sasl/passwd正确。
它应该显示为：
smtp.gmail.com [email protected]:password_or_app_password
设置此文件后，您需要运行postmap它来更新哈希。
postmap /etc/postfix/sasl/passwd
然后重新加载 postfix。
systemctl reload postfix
答案2
我得到了一些帮助，他们发现 passwd 文件没有像 main.cf 文件那样在 smtp.gmail.com 周围加括号，所以我修改了它并使用 postmap 重新映射，然后它给了我一个不同的错误，提到没有可用的有价值的机制，所以我进行了谷歌搜索，发现其他人也遇到了同样的错误，只是安装了 cyrus-sasl-plain 就解决了问题。感谢大家的帮助。
