Yes, almost all of them were "live", no delete or even seen flag set. Of 
course we have backups both tape and offline disks but it got kinda 
tedious with that number of messages :-)

cyradm info:

{user/spamdump}:
   condstore: false
   duplicatedeliver: false
   lastpop:
   lastupdate: 27-Jul-2008 09:58:55 +0200
   partition: default
   sharedseen: false
   size: 0   (there are no msg's at root level, only folders)

I ran the same command on another mailbox and it behaved as I had 
expected, i.e. deleted messages that had sufficient days since expunge.

{user/postmaster}:
   condstore: false
   duplicatedeliver: false
   lastpop:
   lastupdate: 27-Jul-2008 10:42:08 +0200
   partition: default
   sharedseen: false
   size: 2022710

Tried again just now with yet another account and it behaved again fine.
To sum it up, three accounts had emails removed physically that I think 
should not have, the first (spamdump) as it seemed randomly, the second 
and third up till -E days. Two other accounts faired just fine.

confusion.
