I guess your issue is with SQL Mail?
Technically yes - but practically, none of these are enabled, so the end result is the same.
In fact MSDN/BOL regards them to be 'disabled' (MS words not mine)....http://msdn.microsoft.com/en-us/library/ms183753(SQL.90).aspx
True. But this article indicates it's not even installed by default: http://msdn.microsoft.com/en-us/library/ms177418(SQL.90).aspx
