Hi,

First, you should put 'lmtp_downcase_rcpt: yes' into /etc/imapd.conf. This
will do the job for mail delivered to cyrus-imapd. Then, people may
possibly still be able to access their mailbox with uppercase usernames if
you are using ldap with pam for example. If that's the case the mailbox
will be created with upper case on the fly. To prevent from that, I have
made a pam module to deny upper case usernames, look here
http://freshmeat.net/projects/pam_deny_uc/
To use it, I have put this into the relevant pam config files:
auth        requisite     /lib/security/pam_deny_uc.so

Let me know how it goes.
