Voicemail and maildoby configuration

Hello to all,
i have finally configured my Asterisk, and my voicemail accounts work fine!
But i want to translate the body of the mail sent to the users, when he doesn’t respond to a call, form english to italian language.

Seeking the istruction from the voicemail howto that i’ve found in internet, i try to insert in the voicemail.conf these lines:

But the mail is always written in english, and the from string is always ASTERISK PBK, instead of “Centralino” as set in the fromstring variable.

What else can i do?
I really need to send the mail in italian language!!!

Thanks to all for your help!
