Comment (by desmith):

 Let's reduce the scope a bit, then. Latest version just has a function
 called {{{get_email_domain()}}} that returns the domain name, leading www.
 stripped, and that's it. Function name is a bit more clear, at least. All
 the places it's being used are related to email, so the function name and
 its use make a bit more sense.

 If we want to add an if{} to only act if {{{$_SERVER['SERVER_NAME']}}} is
 unset, easy enough to do, but I'm not sure it's necessary.
 Thoughts/opinions?
