Is there a reason this is not "is not" instead of "!=" ?

If you're being Pythonic, a plain "if self.newmail_hook:" would suffice, 
but an equality check with None is very meaningful. It is a singleton, 
so you should be using "is" or falling back to the unadorned 
truthy/falsey bare "if self.newmail_hook:".
