Gettext and Mailer and localized templates

Hi,

my gettext in Edge Rails worked very well, until i localised my Mailer
templates and renamed them like told here:
http://www.yotabanana.com/hiki/ruby-gettext-howto-rails.html
(Localized templates for Views/ActionMailer).

My other templates were localized via _(), not by name.

But then, Rails looked at each action for localized templates, not
only in the mailer.
("Couldn't find template file for users/_user_de in ...")

So I reverted everything, but it didn't work either, rails is still
looking for localized templates.

Does anyone know, how I can manage localized templates only for the mailer?

Thanks,
Beate
