cyrus 2.1.14 supports the option "lmtp_downcase_rcpt: yes". that should
do the trick.

if you haven't got 2.1.14 running, you can use exim's address rewriting
feature. for example, exim can rewrite the envelope to addresses for
local delivery with:

begin rewrite
*@+local_domains        ${lc:$local_part}@$domain       T

this rule downcases the local part of the envelope to, if the recepients
domain is one of your local domains.
