Folders containing messages and subfolders

[Kevin Clark]

Hi,

Does Cyrus IMAP support the ability to have folders that may contain both
messages and subfolders?

The tdlp.org 'MS Outlook to Unix Mailbox Conversion' MINI-HOWTO suggests
that no Linux IMAP server using the Mailbox format supports this feature.

Does Cyrus IMAP use the Mailbox format and, if so, does it therefore NOT
support folders containing both messages and subfolders?

Many thanks,
