ActionMailer method level layouts

I am using layouts in 2.3's ActionMalier.

I know I can specify a layout at the class level:

class MyMailer < ActionMailer::Base   layout 'foo' ... end

Is it possible to define one at the method level?

i.e.

class MyMailer < ActionMailer::Base   layout 'foo' ...   def invite    # USE LAYOUT FOO2   end end

thanks.

render :layout => 'foo'

Are you sure? ActionMailer is a model. Render is for view.

Render is a private method on ActionMailer.

Any one else have ideas on how I can achieve this? Is it possible? (looking at the core source - nothing obvious comes to mind).
