Creating Duplicate mail box.

[Software Groups]

Hi all,


I am using cyrus IMAP for my mail server with auto create folder
option. For some mailbox it automatically creates two mailboxes one
with upper case and one with lower case letter.

For testuser mailbox. I have

t/user/testuser
t/user/TESTUSER


1. How will I force incoming mails to lowercase mailbox?
2. What is the procedure to move Upper case mailbox mails to lowercase mailbox?

Thanks
