Best practice question: ActiveMailer

I’m new to Rails but not MVC programming (very familiar with Struts
for instance.) I’m currently modifying an existing Rails app but I
have some questions about the design decisions that were made in their

The app I’m looking at has an ActiveMailer class but its stored in the
model subdirectory. Does this sound right to people? IMO
ActiveMailer resembles a controller more then it does a model. In
fact, since its deciding which view to render based on the action, its
pretty much exactly like a classic controller.

Apparently Rails when use use the generate script in rails it puts it
in the model directory? Can someone explain the reasoning behind
this? IMO its not a very intuitive choice.
