You can use:
/usr/lib/cyrus-imapd/cyrdump <mailbox> | less
command to dump mailbox. That should also have a list of messages with deleted 
flag.
/usr/lib/cyrus-imapd/unexpunge -l <mailbox>
command should show the list of email which are expunged from the mailbox, but 
still available for recovery. Unlike as with /deleted flag, the recovery of 
expunged emails can be done by Cyrus IMAP addministrator from console only. 
Messages expunged from mailbox are not accessible for user via IMAP in any 
way.
