Email transalated in the user language

[Migrated From Jforum.net]

Hi,
I'm using 2.1.8 version.
I have the folder templates\mail containing the mail messages translated in different languages whit this structure:
templates\mail
de_DE
hu_HU
it_IT
.....
I see in the conf file there are entries like these:

mail.lostPassword.messageFile=mail/lostPassword.txt
mail.lostPassword.subject=[My Forum] Password recovery
mail.messageFormat=text
mail.newAnswer.messageFile=mail/mailNewReply.txt
mail.newAnswer.subject=[My Forum] Message posted\: {0}
mail.newPm.messageFile=mail/newPrivateMessage.txt
mail.newPm.subject=[My Forum] Private Message

so the users receive mails always in the default language or in any case in the language I configured in the jforum-custom.conf file.

Is there a way to send the email based on user language preferences.

TIA
