Sigh...  I must start getting 8 hours of sleep a night.  The situation is
actually more complicated.  The rules (RFC1036 and 822) say that the
domain part -- after the "@" -- is case-insensitive, but the local part --
before the "@" -- is case-sensitive except for some odd special cases.
So one would think that case distinctions in the local part would be okay.
Unfortunately, B2.11 considers *both* parts case-insensitive for some
bizarre reason, and 2.11 is much too widely distributed to ignore.
