Just for the understanding: Cyrus as Dovecot are IMAP-Servers. Each
client, that picks e-mails from each of this servers uses the
appropriate protocol -IMAP (you will find lots of RFC's for this
online). A client NEVER knows (and doesn't have to know), where the
server stored the e-mail-messages. There are Blackboxes as Cyrus,
storing their mails in /var/spool/imap, Dovecot can as i read IMHO
support maildir (var/spool/mail->contains a file for each user) or
mailbox (having a mail-directory in his users directory on the linux-
server and one file per message - if i don't mess).

Also mutt can connect directly via it's imap-functionalty. And if you
want to access those mails via ssh (you really do this???) you will find
all the mails in /var/spool/imap/[users first letter]/user/[username]
and they are numbered. 

Also Cyrus leaves the mails in this directories - this is the advantage
of a imap-server, he reads just the headers first and loads the mail,
once you clicked it...
