邮件服务 的权限问题(igenus webmail)

peoong

大家好,我的web服务器由 apache 改为 nginx 后 igenus webmail 登录后显示有权限问题，报错。

Warning: chdir() [function.chdir]: No such file or directory (errno 2) in /usr/local/apache2/htdocs/acqoomail/list.php on line 24

Warning: mkdir() [function.mkdir]: Permission denied in /usr/local/apache2/htdocs/acqoomail/list.php on line 49

Warning: fopen(list_inbox) [function.fopen]: failed to open stream: Permission denied in /usr/local/apache2/htdocs/acqoomail/list.php on line 62
Error open list_inbox!

请大家帮我看看，要改哪里的权限。谢谢了！
