set in imapd.conf

# Forcing recipient user to lowercase
# Cyrus 2.1 is case-sensitive.  If all your mail users are in lowercase, it is
# probably a very good idea to set lmtp_downcase_rcpt to true.  The default is
# to assume the user knows what he is doing, and not downcase anything.
lmtp_downcase_rcpt: yes
