It's not maildir, but that's the closest thing that I could think of to 
describe it.  Cyrus refers to the mail storage format as mailbox 
directories.  Each message folder is a separate directory.  Each message 
within that folder is stored in a separate file much like maildir, 
however unlike maildir, cyrus messages are stored in numbered files. 
Cyrus also keeps track of who's seen which message (very useful for 
shared folders) and some other "meta" information.  Info available at 
http://asg.web.cmu.edu/cyrus/cyrus-overview.html#recovery.  There is a 
sleepycat database behind it all to map users, etc.

But the most unique thing about Cyrus IMAP vs any other IMAP 
implementation is that the mailbox system is a closed system.  It's 
owned by the cyrus user, and all manipulation is done through the cyradm 
tool or through IMAP commands.
