We had a problem with this several months ago. The alarming aspect of the corruption is when it occurs at the beginning of an email (i.e. ^@^@^@From:...). Emails can be lost/appended to the bottom of the previous email.
Isn't that the delimiter format for one of the other mailbox formats that is a bit like mbox? .. ... I think is it "MMDF" described this page:
Nope. MMDF uses "^A^A^A^A\n" as the separator. ^@ means NUL character.
When Dovecot starts moving data around in mbox file it first increases the file size by writing NUL-bytes to the end of the file (so that no unexpected out-of-diskspace/quota errors can happen). With 0.99.x somehow these NUL-bytes ended up at the beginning of the mbox file.
