the only way around this is to use a trick from SQL, that is to store original
and lower-cased strings, always do the comparison with lower-cased versions but
present the original any-case version.
however, the local_part meaning that PhilipHazel might be a different mailbox
to philiphazel spoils it. You've got to admire the interesting facets of
RFCs sometimes.
I've never met a system which does allow two mailboxes with similar names
though I bet there's one out there somewhere (no wise cracks about MSoft!!).
