We're trying to connect a user's Zimbra account to their Nokia. Setting it up as an Exchange account.

The connection to the server seems to work fine, but the FROM field on the messages seems to be scrambled.

The user sees their messages like this.

From: =?utf-8?B?QmrDtnJuIEkuIEJqw7ZybnNzb24=?= <xxxxxx@xxxxxx.is>
Subject: Prufa
Date: 4. Ma 2012
Time: 9:11:38

From: =?ISO-8859-1?B?U2lncu3wdXIg0y4g3i4gU2lndXLwYXJk83R0aXI=?= <xxxxxxxx@xxxxxxx.com>
Subject: ntt netfang
Date: 3. Ma 2012
Time: 17:54:6

The xxxxx are me just covering up the addresses.

Does the Nokia just not know how to display the FROM properly?
