限制 linux 帳號在 postfix 寄信或收信
限制寄信:
在 /etc/postfix/main.cf 加入 smtpd_sender_restrictions = hash:/etc/postfix/access 讓 access 有作用
在 /etc/postfix/access 加入 user@ REJECT sorry,we don't provide smtp service for you 這樣 user 帳號就不能寄信
最後更新 access.db 指令 postmap /etc/postfix/access 及 重啟 postfix 指令 /etc/rc.d/init.d/postfix restart 就 OK 了
限制收信:
在 /etc/postfix/aliases 加入 user: /dev/null 將 user 的來信丟掉,這樣 user 就收不到信
最後更新 aliases.db 指令 newaliases 及 重啟 postfix 指令 /etc/rc.d/init.d/postfix restart 就 OK 了
