Hi guys,
this page needs to be updated: https://wiki2.dovecot.org/MailLocation/Maildir#Control_files
(link was from here: https://wiki2.dovecot.org/MailLocation)
Section 'Control files' is mentioning only 2 files but, in fact,
Dovecot will store some additional files in CONTROL location:
dovecot-uidvalidity
dovecot-uidvalidity.*
subscriptions
(anything more?)
Even more, page https://wiki2.dovecot.org/MailLocation has missing
note to CONTROL files location about storing files 'dovecot-uidlist'
and 'dovecot-keywords' of INBOX inside .INBOX directory instead of
root directory (as it's stored inside mailbox).
Missing anything from above will cause re-downloading of all e-mails
by e-mail clients!
And finally, i'm attaching a Python script which will safely copy/move
CONTROL files from mail_location to new location (btw, moving it on
SSD storage caused quite high performance boost in our environment).
