I have two accounts where the inboxes sometimes get corrupted. In that case they begin with "FFrom".
I saw similar reports in July/August last year. So I applied the patch http://dovecot.org/pipermail/dovecot/attachments/20100720/e87b32ae/attachmen...
Yesterday a mbox corruption happened again. Here are the log lines.
