Retrieving mail from old damaged database

[nez_bit]

We are running a 10.3.9 server. The mail server keeled over in the middle of the day today. The system log shows imap database errors, and shows that reconstruct failed etc.
I tried a manual reconstruct which failed, but I cannot remember the error now. Panic started to set in a little !

Anyway, I’ve had to resort to starting up again from last nights duplicte of the system, which leaves me with 12 hours worth of email missing. Is there anyway to try and get the email out of the possibly o.k. mailboxes from the “damaged system” drive, which has a system that isn’t active. It’s just a second drive in the now working mail server.

i’d try making a copy of the old mail store.
then remove each folder’s cyrus.cache, cyrus.header and cyrus.index file.
sudo find /path/to/imap-copy/ -name ‘cyrus.*’ -delete
should do the trick
next use the standard reconstruct tools, then try to specify this as an alternate mail store
set up a test user and see how it goes…
