We have also "To" and "To:" so that should be no problem.
The problem left is, that the "old" field names ("to") are stored in the prefs. 
If we change the naming of the fields the old prefs won't work any more and 
even worse: will produce errors.
A way to handles this would be to translate the old field names to the new ones 
if we find already stored old prefs. But is this worth for back compatibility?
