Hi list, today a user reported messages are disappearing from his INBOX and I discovered a two digit number of mailboxes with broken dovecot-uidlist files.
The log says: Oct 29 08:51:34 mail02 dovecot: lmtp(i...@example.com)<5270><QOoVJIbvt12WFAAAJOVBUw>: Error: Mailbox INBOX: Broken file /var/vmail/example.com/info/dovecot-uidlist line 88: Invalid data: And the respective files do look broken: 4596 :1572344253.M529133P14861.mail03.example.com,S=53053,W=54233 ^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@4597 :1572344797.M93833P15905.mail03.example.com,S=126866,W=129256 Setup : Behind a director I am running two dovecot backend servers sharing the vmail directory via NFS. Do you have an idea where this might come from? How can I debug this further? Cheers, Dirk
