ACL troubles

[Andy Hall]

We're trying to block web-based mail from lab and open computers for our 
kids.  Below is my squidguard.conf.  It seems that only the 'school' source 
area is taking affect.  If I put the '!mail' in with the school acl, things 
are peachy.  Don't want to block everyone from the web-mail though.


Suggestions anyone?
