After a (power)crash two accounts have been corrupted. I tried to rescue things by running force-resync multiple times, but that didn't work out. Searching the archives, I found a recent suggestion (by Timo) to delete the index files, but I'm not sure which files to delete and what the consequences will be. When I deleted ``storage/dovecot.map.index'' in an unimportant account of my own, things only grew worse and I decided to delete the account and start fresh...
Something I obviously don't want to do with the other account as it belongs to a client with about 2.5G mails (856 m.* files), which we don't want to lose.
I have observed the following behavior in the logs: When a new mail arrives: (The second line below is always the same, however there's no mail with uid 12819 according to doveadm search uid 12819) Mar 04 11:43:28 lda(user): Warning: mdbox /var/mail/user/storage: Inconsistency in map index (117,1060 != 117,1883660) Mar 04 11:43:28 lda(user): Error: Log synchronization error at seq=117,offset=1546660 for /var/mail/user/storage/dovecot.map.index: Extension record inc drops number below zero (uid=12819, diff=-1, orig=0) Mar 04 11:43:28 lda(user): Warning: fscking index file /var/mail/user/storage/dovecot.map.index Mar 04 11:43:28 lda(user): Info: msgid=d760229d563e99dc787acd0746b18b31@feedback.1dayfly.net: saved mail to INBOX Mar 04 11:43:28 lda(user): Warning: mdbox /var/mail/user/storage: Inconsistency in map index (117,1060 != 117,1883784) Mar 04 11:43:28 lda(user): Warning: fscking index file /var/mail/user/storage/dovecot.map.index Mar 04 11:43:28 lda(user): Warning: mdbox /var/mail/user/storage: rebuilding indexes Mar 04 11:43:28 lda(user): Warning: fscking index file /var/mail/user/storage/dovecot.map.index Mar 04 11:43:28 imap(user): Error: /var/mail/user/mailboxes/INBOX/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 04 11:43:28 imap(user): Info: IMAP session state is inconsistent, please relogin. in=2011 out=108358 deleted=0 expunged=0 trashed=0
When user logs in next (might be from another box/MUA)
Mar 04 11:44:36 imap-login: Info: Login: user=<user>, method=PLAIN,

Besides the nuisance of getting kicked of every time a new mail arrives, user cannot delete mails (as in: move to Trash).
TL;DR: which files to delete and what will be the consequences?
