Multiple Mail identities

[gravasio]

Hello,
i'm trying to add more mail identities to an openexchange user using this command:
./changeuser -c 1 -i 10 -a giuseppe_ravasio2@test.com,testnoc@test.com -A oxadmin -P test

I have the new identity in OpenExchange, but it seems that i cannot change the real name, in fact:
"Giuseppe Ravasio" <giuseppe_ravasio2@test.com>
"Giuseppe Ravasio" <testnoc@test.com>

but i need to change the from real Name! I need something like:
"Giuseppe Ravasio" <giuseppe_ravasio2@test.com>
"NOC" <testnoc@test.com>

It's a group mail identity, there is a way to have this configuration?

Thanks
Giuseppe
