When using scandinavian characters on body of the message, those get
messed when sending to addresses outside GW.
Works ok for subject line, subject seems to be using UTF8.

When looking at source of MfE + GWMobility message it shows:
Content-Language: i-default
Content-Type: multipart/mixed;

While normal GW messages shows:
Content-Type: text/plain; charset=UTF-8
