Before your mail, I would also have been for keeping the status quo
(Since I remembered that local parts are case sensitive according to
internet standards). However, your mail has rectified my memory, and I
would tend to change the default, even if upstream doesn't do so.
However, we should do this in a way which doesn't interfere with
existing installations (don't cause breakage by updates within the same
major release - 2.2). In other words: Leave the default value in the
binary as is and change the packages imapd.conf to include a:
lmtp_downcase_rcpt: 1
