終於成功配置了sendmail為本地使用者轉發郵件

在ubuntu中安裝了sendmail，通過bind在本地管理域student6.org的域名。在給本地使用者mailtest傳送郵件時，總會收到這樣的郵件內容：

553 5.3.5 mail.student6.org. config error: mail loops back to me (MX problem?)
554 5.3.5 Local configuration error
整了好長時間都沒有整好，根據上面提示內容“loops back to me”，覺得應該是sendmail沒有意識到student6.org是本地的域，開始不相信，因為我已經在/etc/mail/local-host-names中填寫了student6.org這一行。後來實在不行，在/etc/mail/sendmail.mc加入一行：
LOCAL_DOMAIN(`student6.org')
來確保這個域被sendmail認為是本地域，終於成功了！SIGN~~~~~~~
