Yes, and inside that directory you'd make a registration_mail.rhtml 
(the same name as your mailer) that is the body of your template.

You also need to put the the body variables you want available to the
template in a hash. So it would look something like this:

    def registration_mail(to, user, password)
         [...snip...]
        @body[password] = password
        @body[username] = username # this way you can have multiple
variables passed to the template.
    end

You don't actually call the registration_mail method directly. You
would call it as:

    Notifier.deliver_registration_mail(...)

This method is created automatically by ActionMailer. It's mentioned
here in the ActionMailer README:
http://am.rubyonrails.org/files/README.html (Directly above the
'Dependencies' header)

When called this it uses the template with the same name as the mailer
method automatically. You don't need to call 'redirect_to' (which
would redirect the users browser instead of sending a mail anyway).

Hope that helps.
