1. The definition of 'mail' in RFC 4524 also defines case-insensitive matching
rules. Mainly the text pointing out the issue was taken from RFC 4524.

2. All applications are used to that. Note that the most important use-case is
searching for / completing an e-mail address. Case-insensitive matching by
default is more comfortable for that.

3. I'd rather expect only very few cases in which somebody want to add

intlMailAdr: [email protected]
intlMailAdr: [email protected]

to a *single* entry meaning two *different* mailboxes. Do you know of any
deployment like this? What would be the semantics for that?
Note that 'intlMailAdr' is not meant as multi-valued attribute for mail group
entries for which such a case would be slightly more likely.
Also note that case-insensitive matching is a different thing to
case-preserving storage. I will add a note about the latter.

I'd appreciate if you propose text making this more clear if you feel it's needed.

Thanks. Updated all occurences in next version.

Ciao, Michael.
