Let's say I keep Squirrelmail but I don't want to use the  
functionality of writing to that config file with apache. How do I  
undo this? I just wanna give it a try and I'll probably want to  
revert the changes I made for SElinux.
So what would be the opposite of chcon -t httpd_squirrelmail_t /usr/ 
share/squirrelmail/config/config/ php to undo the changes it makes?

Thanks
