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(info@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
