restoration of mailboxes

[Sebastian Reitenbach]

Hi list,

I have to restore a users mailbox with some subfolders. Because of a crash of 
the client, maybe the half of the inbox, and maybe subfolders are gone. The 
mails are gone in random order, so I have no clue which of these many mails 
are gone.

Is it save, when I restore the NNN. files from backup, and run a 
reconstruct -r user.mailboxname. 

Is this safe to do this while cyrusd is running, or do I have to stop it?
Are the flags, e.g. read, flagged, ... of all the mails in the mailbox 
affected by running reconstruct, or only the ones that are new from the 
backup?

kind regards
Sebastian
