我无法接收来自外部邮件地址的电子邮件。发送邮件和接收来自本地邮件地址的邮件都正常。在 /var/log/maillog 中，我收到以下错误：

知道错误的原因是什么吗？

我已经修复了我的问题。如评论所述，相应的 Bug 报告是https://bugs.centos.org/view.php?id=12393。
修复程序评论Yohei TOMIYAMA 的作品对我有用。
在修复之前，请确保它是同一个错误。软件包的以下版本必须匹配：
yum list installed | grep pypolicyd-spf
pypolicyd-spf.noarch 1.3.2-2.el7 @epel
yum list installed | grep python-ipaddress
python-ipaddress.noarch 1.0.16-2.el7 @base
python-ipaddress 软件包可能仅由 pypolicyd-spf 需要，否则此修复将破坏其他任何内容。您可以使用以下方法检查
rpm -q --whatrequires python-ipaddress
pypolicyd-spf-1.3.2-2.el7.noarch
现在修复：
rpm -e --nodeps python-ipaddress
vim /usr/libexec/postfix/policyd-spf
在第 40 行将该行修改如下：
- import ipaddress
+ import ipaddr as ipaddress
就是这样。根据邮件提供商的配置，他们会间歇性地重试发送邮件。大约一小时后，大多数丢失的邮件应该会收到。
如上所述，感谢 Yohei TOMIYAMA 提供此修复。
