The following is a quick and dirt guide on how to use a mailbox with the “.” character with Cyrus Imap.

add the following line to your imapd.conf

unixhierarchysep: 1

login to your cyrus imap server and run the following command to create a new mailbox

cm user/your.name

setacl user/your.name cyrus lrsiwpcda 

When the UNIX hierarchy convention is used, the “.” character MAY be used in mailbox names, including user names. In order to mantain backwards compatibility with the internal namespace, all “.” character will be translated in a benign character (at this time “^”) before any data is written to disk. For example, if user “your.name” had a personal mailbox “customer.support” , it would be stored as “user.your^name.customer^support” in the internal namespace.

If you use it, it’s very important that you remember this phenomenon if/when reverting back to the netnews hierarchy convention.

Hope this help
