Timo, I've changed postfix lmtp delivery config to deal with storm conditions (oleg's emails), so that other users didn't wait for their email for hours. lmtp_destination_recipient_limit = 1 Number of error messages had dramatically reduced. It looks like concurrency is the root cause of the problem. I'm rebuilding oleg's mailbox just in case something was broken. dovecot.index.cache files looks tiny now -rw------- 1 vmail vmail 7,9M ????. 23 18:39 ./mailboxes/INBOX/dbox-Mails/dovecot.index.cache
