Fedora
Fedora 上的 Postfix 不遵循別名
我創建了一個腳本來安裝 Postfix，它可以完美地與我所有的 Ubuntu 客戶端配合使用，但不適用於我的 Fedora 客戶端。
Fedora 客戶端能夠直接向 user@domain.com 發送電子郵件，但是當發送到 root 時，它應該被重定向到 user@gmail.com，而是被發送到 root@freesoftwareservers.com
我一生都想不通為什麼……如果有人能指出這個很棒的問題，這裡是配置和日誌。

好吧，我過去曾使用過它，但這次嘗試在設置 Postfix 時減少我的配置。我不確定為什麼 Ubuntu 不需要它，但 Fedora 需要它，但這就是我修復它的方式。
/etc/postfix/main.cf:
canonical_maps = hash:/etc/postfix/canonical/etc/postfix/規範：
root user@gmail.com重新載入 Postfix 並測試！–>
postmap /etc/postfix/canonical && postfix reload
