Maybe I am wrong but it seems to me that the email address in a
certificate must match the email address on the message which match
includes the CASE of letters in the address. So if I have a bunch
of user names I entered in Address Book, like - ages ago, and now I
am accumulating certificates which have the same email address, but
with a different case, there is no match when I send to some whose
certificate I actually have. Mail, or keychain, will not see it.
Email is classified as "Case Preserved" in that all matching is
done in the same case but the way the address is entered by the
user is "passed through." So email@hidden is the same
as email@hidden as far as an email engine goes. But
not for certificate identification on the Mac it seems.
Actually, no. According to the standards, the local-part (LHS of the
@) of an email address is case-sensitive. So
email@hidden and email@hidden are,
according to the RFCs, different email addresses.
Now, it's common in both MTAs and MUAs to treat the local-part as a
case-insensitive string, but that's not *strictly* correct. Apple
has been strict in this case.
