我在 Postfix 中設定別名“support-notify”時遇到問題。
收件人地址被拒絕：存取被拒絕；
我在 Ubuntu 18.04 LTS 上運行帶有 OpenDKIM、OpenDMARC、Policyd-SPF 和 Dovecot 的 Postfix。
地圖在 /etc/aliases 中看起來像這樣
support-notify: user1, user2, user3
使用者 support-notify 不存在，而 users1-3 是伺服器上擁有郵箱的實際使用者。
我已包含postconf -n在下面。
postconf -n

答案1
你的/etc/aliases線路看起來不錯，配置也不錯。
alias_maps = hash:/etc/aliases
既然是hash:ie Berkeley DB，你還記得這個指令嗎：
postalias /etc/aliases
答案2
我決定放棄我的整個 postfix 配置並重建它以利用虛擬用戶/網域和 mysql 作為資料庫。
