Depends on the purpose of the name(s).

If you run everything on a single host, then mail.example.com.

If you need to distinguish mail routing from other tasks (e.g. when 
running a spam filter on a different host and you want to tell other 
smtp servers to deliver to that instead of directly to your main mail 
server), then mx.example.com (or mx1.example.com) for that.

Similar for other names: Use protocol or other special name to emphasize 
that service, otherwise it is more confusing than helping.
