什么名字会给一个愚蠢的数据类?

I'm writing a pretty simple email mime parser for an application I'm developing, and was thinking it'd be a good idea to create a dumb data class to make as 'an email' but as an object.

This is all well and good, and this might be a terrible question for SO, but alas, I am asking anyway. What would you call said dumb data class?

As I'm writing the project in Symfony 2.2 I thought using the word 'Entity'; as broad a term as it is, wouldn't make as much sense and could cause confusion because of Entities being used in DocTrine. So, what's the term that's used for this kind of thing? Just to store data and potentially use methods on it, like an entity, to format or retrieve other bits of information.

If you use the class just to pass data around, that's a DTO (Data Transfer Object from Java) in my opinion.So EmailDto could work
If you add methods to it i'd just use Email as the name of the class, just to describe what is.

Generic names for classes are things like Object, Entity, Thing, Data, Class, Handler, etc. Descriptive names are really good to avoid confusion, though. YMMV

How about calling it (the Germans among us are free to ROFL ;-) ):
