bugzilla在用了几个月后，不能发送邮件了

wumaosen

环境：本人是在linux下安装的bugzilla,相关组件有appache,mysql,sendmail.
问题描述：
本来，有提单的时候，都可以自动把邮件发邮到指定的人那里。
现在，每次提单，或者修改时，页面都无法跳转。并且有错误提示：
提单跳转后是这个页面：http://10.8.1.12/post_bug.cgi
显示如下错误：
Internal Server Error

Please contact the server administrator, root@localhost and inform them of the time the error occurred, and anything you might have done that may have caused the error.
