我设置了 postfix + dovecot 并且知道我想要邮件列表，所以我决定安装 mailman。
一切正常，除了我无法向我的邮件列表发送电子邮件（这很重要，你不觉得吗？）。
当我向我的邮件列表发送邮件时（[电子邮件保护]），我收到一条回复“未送达的邮件已退回给发件人”，内容如下：
This is the mail system at host too.gy.
I'm sorry to have to inform you that your message could not
be delivered to one or more recipients. It's attached below.
For further assistance, please send mail to postmaster.
If you do so, please include this problem report. You can
delete your own text from the attached returned message.
The mail system
<[email protected]>: unknown user: "[email protected]"
看起来 Postfix 正在尝试验证我的邮件列表地址，但显然该地址未在 Postfix 用户数据库中注册。
但我在安装过程中遵循了说明，但我不知道为什么会发生这种情况。我浏览了所有讨论此问题的邮件列表，但仍然无法正常工作。所以我来了。

答案1
您已mailman在 下正确添加了别名alias_maps = hash:/etc/postfix/aliases, hash:/var/lib/mailman/data/aliases。但您已覆盖您的local_recipient_maps。只需local_recipient_maps在您的 中按如下方式修改您的main.cf，因为本地收件人将在 中进行搜索local_recipient_maps。
local_recipient_maps = $virtual_mailbox_maps $alias_maps
答案2
我按照ArchWiki 页面tgy 提到。我的解决方案是：
- 删除
local_transport = virtual行 $mydomain从......中去除mydestination
来自 Postfix' main.cf，以及
- 设定
VIRTUAL_MAILMAN_LOCAL_DOMAIN = 'localhost'在 Mailman 的mm_cfg.py - 重新运行
/usr/lib/mailman/bin/genaliases（现在生成表单list-*@localhost）。
解释：将本地传输设置为virtual，Postfix 被指示将所有与 Mailman 相关的邮件传递到虚拟邮箱（不存在该名称的邮箱）。
随着local_transport回到其默认值，可以本地交付给 mailman 脚本（这localhost是 的一部分mydestination）。但是解析我的虚拟邮箱（数据库帐户）仍然有效，因为域是通过提供的virtual_mailbox_domains（因此会出现重复警告）。
