Most likely not, but that is such a well know script, why not disguise a little further? - just in case...

PHP Code:
  var recipient "e-mail"
  
var z1 "user";
  var 
z2 "domainname";
  var 
z3 "com";
  var 
s1 "@";
  var 
s2 ".";
  
document.write("<a href=" "mai" "lto:" +z1+s1+z2+s2+z3 ">" recipient "</a>" "!"
In fact, I tend to avoid 'email' as a name of a var anyway, because some bots reading the form can figure it out and start hitting the form with a POST of their own.
