I don't really understand why deleting dovecot.index* would make a difference here, except maybe as a workaround in case the user has that mailbox selected, because the filenames could be cached in memory. http://dovecot.org/tools/maildir-size-fix.pl http://dovecot.org/tools/maildir-size-check.sh Those scripts kind of do what you want, except not fully, so it would be nice to get one fully finished one :) The best way for the script to would would be to: * scan through a maildir, figure out what needs to be renamed to what, but don't actually do it * lock the maildir with dovecot-uidlist.lock (src/util/maildirlock comes with dovecot) * doveadm kick user's imap/pop3 sessions, and even better if it was possible to kill -9 any pending processes * rename the files and update dovecot-uidlist * delete dovecot-uidlist.lock This separately for each folder.
