I am trying to track down an mbox corruption issue that has been happening for one of our users. It appears that the mbox file is getting truncated and the all important From line no longer exists which then leads to the mbox being useless. It also appears, as in most truncations, that parts of the mbox are being lost.
Can you give me some specific examples of what the corruption looks like? For example you could put the mbox through http://dovecot.org/tools/mbox-anonymize.pl
I am not sure how to debug this to find out whether this is a client or server issue and any pointers would be appreciated.
Client can't corrupt mailbox data no matter what they do. But it's possible that the user/client is doing something a bit differently than everyone else and that causes it.
What OS and filesystem do you use? It's a local filesystem and not NFS or something? Does Dovecot log any errors (about anything)?
