Thanks. Losing 300 flags and unread on thousands of emails was not a preferred 
scenario.

I was able to repair by 
- turning dovecote (and other mail services) off
- find all message files that were changed in a certain period
- check all their names against their file sizes (this found me the edited ones)
- returning the ***UNCHECKED*** string to the Subject lines making the file 
sizes equal to the size as reported in the name of the file 

Which leaves me with something I would really like: change the subject line of 
5-10 messages in dovecot, without destroying everything.

I was thinking about the following scenario:
- create a separate mailbox REPAIR within user X’s mail store (the INBOX, btw, 
is named ‘cur’)
- move all to be changed messages there using the mail client
- kill the mail client
- stop dovecot
- edit the messages and change the names of the files so the S= W= parts are in 
line with the new content. (I understand S, but what is W?)
- run “devoid index -u user REPAIR”
- start dovecot
- start email client (potentially, reload the entire mail store for that user)

Would that work?
