translations

by the way, some people said that when they sign up, the notification email is on english, I check that and this part is already translate (app/views/devise/mailer/confirmation_instructions.html.erb).
Similar problem happens when people subscribe to a place and recive notifications , most part of the mail is translated but the CONFIG.logo and the CONFIG.site_name is coming from iNaturalist, do you think can be configure to send mails from NaturaLista?  well thanks and saludos.
