电子邮件地址标记不适用于 Postfix 中的虚拟邮箱

我有自己的电子邮件服务器，我希望能够使用动态电子邮件地址标记。我recipient_delimiter = +-向配置中添加了该指令并重新启动了 postfix，但现在如果我发送电子邮件[email protected]，电子邮件将被退回，并显示错误“未知用户”。如果我发送电子邮件，电子邮件将按预期[email protected]发送到帐户。webmaster

这是我的 postfix 配置：

## These are all default Postfix settings that we won't change

从/etc/postfix/master.cf，我有这个定义的 Dovecot：

dovecot   unix  -       n       n       -       -       pipe
  flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver
  -f ${sender} -d ${recipient}

我还对、、、、、、、以及其他一些定义进行了定义，ifmail但我bsmtp不完全确定它们的作用。scalemail-backendmailmanuucpscachemaildrop

有人知道这里发生了什么事以及我该如何解决吗？

我正在使用虚拟邮箱。

在/etc/postfix/master.cf配置文件中，确保配置参数dovecot引用的服务定义设置virtual_transport为在调用期间抑制收件人地址的扩展部分/usr/lib/dovecot/deliver。

例如，这可能不起作用，因为${recipient}将被[email protected]Postfix 的管道(8)服务：

dovecot   unix  -       n       n       -       -       pipe
  flags=DRhu user=dovecot:dovecot argv=/usr/lib/dovecot/deliver -f ${sender} -d ${recipient}

在这种情况下，应该将宏${recipient}替换为${user}@${domain}，以便 Dovecot 传送代理[email protected]在其命令行中接收正确的地址：

dovecot   unix  -       n       n       -       -       pipe
  flags=DRhu user=dovecot:dovecot argv=/usr/lib/dovecot/deliver -f ${sender} -d ${user}@${domain}

参数中的多个字符recipient_delimiter似乎仅在 Postfix 2.11 或更高版本中受支持。请确保您正在运行较新的 Postfix 版本，或者仅使用一个分隔符。

从postconf (5)手册页：

收件人分隔符（默认：空）

一组字符，用于将用户名与其扩展名（例如：user+foo）或 .forward 文件名与其扩展名（例如：.forward+foo）分隔开。基本上，软件会先尝试 user+foo 和 .forward+foo，然后再尝试 user 和 .forward。此实现会为每个电子邮件地址或 .forward 文件名识别一个分隔符和一个扩展名。

当recipient_delimiter集合包含多个字符（Postfix 2.11及更高版本）时，用户名或.forward文件名与其扩展名之间以与recipient_delimiter集合匹配的第一个字符分隔。
