请大家帮我看看，要怎么改！

Warning: fopen(/home/vpopmail/domains/acqoo.com/patrick/Maildir/./new/1289965578.20492.look,S=2352) [function.fopen]: failed to open stream: Permission denied in /usr/local/apache2/htdocs/acqoomail/list.php on line 213
error open file
Warning: fgets(): supplied argument is not a valid stream resource in /usr/local/apache2/htdocs/acqoomail/include/fun_inc.php on line 77

Warning: fclose(): supplied argument is not a valid stream resource in /usr/local/apache2/htdocs/acqoomail/list.php on line 222

刚刚发的邮件的权限
-rw------- 1 vpopmail vchkpw    2425 11-17 12:04 1289966646.20832.look,S=2425:2,
将它改为 -rwxrwxrwx  就不会出现上面的错误了，就正常了。。

求解:要怎样改权限啊！
