Thanks Ryan,
 
I'll try that one. So if I didn't use -o, then the new rule must come
before the alert, am I right?

        Ronneil,
        
        I didn't see a reply to your post, but you have a couple of
different
        options including commenting out the rule with # in front of it,
or adding a
        pass rule to ignore the rule when it matches given criteria
        
        To ignore alerts for SMTP traffic, your pass rule might look
like:
        
        pass tcp any any -> any 25 (msg:"ATTACK RESPONSES id check
returned root";
        flags:A+; content: "uid=0(root)"; classtype:bad-unknown;
sid:498; rev:2;)
        
        (Sorry for false alarms guys, needed to keep the rule content
for the
        example.)
        
        Remember, you'll want to change snort's rule processing order if
you decide
        to use pass rules: snort -o
