You use "allow_class" in the wrong way:

  "encode_base64" is not a class but a function.

  "allow_class" sets security declarations such that the
  attributes of instances of this class can be accessed
  without restrictions. However, there are no instances
  of a function...

What you almost surely want is:

     ModuleSecurityInfo('email.Encoders').declarePublic('encode_base64')
