AddressValueError，Dovecot不能接收外部邮件

Question

更新后

从dovecot-1:2.2.10-7.el7.x86_64到1:2.10-8.el7.x86_64

从dovecot-mysql-1:2.2.10-7.el7.x86_64到1:2.10-8.el7.x86_64

从多维柯-鸽子洞-1:2.2.10-7.el7.x86_64到1:2.10-8.el7.x86_64

我无法接收来自外部邮件地址的电子邮件。当从本地邮件地址发送邮件时，发送邮件和接收邮件一样工作正常。在/var/log/maillog中，我有以下错误：

知道错误的原因是什么吗？

Answer 1

我已经解决了我的问题。正如注释中所述，相应的Bug报告是https://bugs.centos.org/view.php?id=12393。

由Yohei在评论中提供的修复为我工作。

在修复它之前，确保它是同一个错误。以下版本的包必须匹配：

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

软件包可能只需要pypolicyd-spf，否则此修复将破坏任何其他内容。你可以用

rpm -q --whatrequires python-ipaddress
pypolicyd-spf-1.3.2-2.el7.noarch

现在的解决办法：

rpm -e --nodeps python-ipaddress
vim /usr/libexec/postfix/policyd-spf

在第40行，将行修改如下：

- import ipaddress
+ import ipaddr as ipaddress

就这样。根据邮件提供者的配置，他们会尝试隔一段时间发送邮件。大约一个小时后，大部分丢失的邮件都会收到。

如前所述，感谢Yohei提供了此修复。
