Use printk(). It works like printf for the most part.

Example: printk( KERN_DEBUG "Hello World!\n" );

Where KERN_DEBUG is one of the priority levels defined in
<linux/kernel.h>

P.S. If you are using sendmail, try changing /etc/sendmail.cf
CMshoukui.pku.edu.cn
DMpku.edu.cn
This will cause all mail from: shoukui.pku.edu.cn
to be appear to be from: pku.edu.cn
