無法收取外部郵件問題
我用Postfix和Mysql在RHEL4上搭建了一個Mail Server,原來是aaa.com，收發郵件都能夠正常使用，現在增加了一個bbb.com的虛擬域，通過postfixadmin建立的。現在通過bbb.com發郵件都正常，也能夠收取內部郵件，包括從aaa.com發送過來的郵件。但從外部郵箱如163.com或hotmail.com發送的無法收取。各位大大幫我看看是什麼問題。主機名為mail.aaa.com dns解析也都能解析到aaa.com和bbb.com的MX記錄
附上main.cf和外部郵箱退信信息：

回復 #1 kamioyoung 的帖子
你需要把伺服器放在公網（有個公網ip），再正確配置你的域名才可以收郵件
《解決方案》
伺服器是在公網上的，原來也能夠正常收發郵件的，我寫的aaa.com和bbb.com只是把真正的域名隱藏掉了。

有<test@bbb.com這個用戶嗎
