具有多个条目的 Postfix Maildir virtual_mailbox_maps 和 virtual_alias_maps

使用 Ubuntu 16.04 Xenial / Postfix 3.1.0 我已经设置虚拟邮箱映射和虚拟别名映射使用邮箱目录我需要 Postfix 将邮件同时发送到外部电子邮件地址和相应的 Maildir 文件夹。相反，尽管我尽了最大努力，Postfix 还是选择了第一个匹配/出现。它要么将邮件发送到别名，要么将邮件发送到 Maildir。我无法将其配置为同时执行这两项操作。

这个问题的第二部分是，我还需要将一个虚拟邮箱转发到多个 Maildir 位置。例如，我需要将邮件发送到[电子邮件保护]将邮件存储在 /home/vmail/mydomain.com/admin/ 和 /home/vmail/mydomain.com/backup/ 中（除了转发到外部电子邮件地址[电子邮件保护]如上所述）。

尝试这样做会导致在第一个 Maildir 中创建一个子目录，其名称与第二个 Maildir 相同，并将收到的邮件存储在那里。我尝试使用空格、制表符、逗号和加号分隔条目。每次尝试都得到相同的结果，即在 /vmail/domain.com/user/ 文件夹中创建一个子目录。每次更改后，我都会使用 postmap 并重新加载 Postfix。

我也尝试为单个地址添加多行，但 Postfix 会读取第一个匹配项并发出有关重复的警告。

虚拟邮箱映射// 我尝试使用空格分隔，如下所示：

[email protected]    mydomain.com/admin/   mydomain.com/backup/

注意，上述格式适用于虚拟别名映射，转发至多个外部电子邮件地址。

我搜索了互联网上能找到的所有资源，尝试了各种不同的配置。我当前的 main.cf 配置如下。我暂时注释掉了 virtual_alias_maps 以保持 Maildir 配置的功能（别名似乎总是优先）。

非常感谢任何建议或帮助。如果需要更多信息，请告诉我。

答案1

看起来 virtual_alias_maps 可能就是答案。

您只需要在 virtual_alias_maps 中像这样指定它：

[email protected] [email protected], [email protected]

当然，你应该[电子邮件保护]在 virtual_mailbox_maps 中。

我在这里找到了答案（示例 2）：https://workaround.org/ispmail/jessie/types-of-email-domains
