This is a clear case for lazy imports; perhaps something like this in 
email/__init__.py:

import sys

class LazyImporter(object):
  def __init__(self, module_name):
      self.__module_name = module_name

  def __getattr__(self, name):
      __import__(self.__module_name)
      mod = sys.modules[self.__module_name]
      self.__dict__.update(mod.__dict__)
      return getattr(mod, name)

sys.modules["email.MIMEText"] = LazyImporter("email.mime.text")
...
