Except the whole point of surveying people was to see if anyone out  
there actually *uses* the fact that IMAP usernames are case sensitive.

So the proposal is definitely to normalize all usernames in Horde.  
That would make IMP, as a side effect, not usable on imap servers  
where duplicate-except-for-case usernames are used.

Given feedback from people (no one seems to rely on that), I think  
this is a good tradeoff.
