感謝，或許真的是這樣，我試試看，再跟大家報告。

感謝二位的回覆...
/var/mail 的空間還有好幾G，而mail server也有在使用當中，目前猜測應不是lifetype的問題....
我在查查看好了....^_^....

各位大人好，小弟目前遇到一個問題，就是迴響後收不到自動通知的mail......

環境是 FC3 + mysql-3.23.58-16.FC3.1 + httpd-2.0.53-3.3 + php-4.3.11-2.8 + gd-2.0.28-1.30.1 使用php mail()...

但當有人迴響後，在server的 maillog 裡都會有如下的錯誤訊息.....

/var/mail 的權限是 775，雖說permission denied，但是看了很久，仍然不知所以然，知那裡有問題，各位大大，可以給個方向嗎！
感謝
