電子郵件地址標記不適用於 postfix 中的虛擬郵箱

我有自己的電子郵件伺服器，我希望能夠使用動態電子郵件地址標記。我將recipient_delimiter = +-指令添加到我的配置並重新啟動後綴，但現在如果我發送電子郵件bob+sometaghere@starbeamrainbowlabs.com，電子郵件將被退回，並顯示錯誤“未知使用者”。如果我發送電子郵件unknownuser@starbeamrainbowlabs.com，電子郵件將按預期發送到webmaster帳戶。

這是我的後綴配置：

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

從/etc/postfix/master.cf，我有這個定義的 Dovecot：

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

我也有 , , , , , , 和一堆其他的定義ifmail，bsmtp但scalemail-backend我mailman不uucp完全scache確定maildrop它們都做了什麼。

有誰知道這裡發生了什麼以及我該如何解決它？

我正在使用虛擬郵箱。

在/etc/postfix/master.cf配置文件中，確保配置參數dovecot引用的服務定義virtual_transport設置為在呼叫/usr/lib/dovecot/deliver.

例如，這可能不起作用，因為${recipient}它將被bob+sometaghere@starbeamrainbowlabs.comPostfix 的pipe(8)服務擴展為：

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

在這種情況下，${recipient}宏應替換為${user}@${domain}，以便 Dovecot 傳遞代理bob@starbeamrainbowlabs.com在其命令行中接收正確的地址：

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