ActionMailer outside of Rails?

Does anyone know of issues using ActionMailer outside of Rails? I'm
already selectively using ActiveRecord, so I thought perhaps I could use
ActionMailer as well. (To solve one of those last minute "And could you
make the app email me if it throws any errors" questions that was never
in the original spec...)

Is this what your looking for?
