Well, it is a bug and it shouldn't happen. But since it happens only with mbox, 
I haven't bothered to look into it.

This account is used by multiple users, but it is not a shared account
(haven't set any of those up yet - still new to me), so I would expect
corruption possibilities when multiple users modify the account folders
in some manner.


This is just one dovecot IMAP client process moaning after another user
client process pulled the rug out from under it by modifying the mailbox.
I get a few dozen log entries of this sort per week with ~200 IMAP users
without shared access.

Unless your users actually complain about a problem, I think it's safe
to ignore them.

It is customary to provide at least some bare minimal system details, 
like, dovecot -n output (which includes the version), platform/OS, etc...

Still new to dovecot,

I'm seeing a couple of errors in my log file indicating corruption of 
index files.


Error: Corrupted index cache

for mail UID 67: 1 Time(s)

Error: FETCH [] for mailbox ~/mail/sent-mail UID 67 got too little data: 6203

Until I get some experience under my belt and make this a truly "shared" 
account, is there any way to resolve the corruption of the files 
mentioned above? Maybe just delete them?


thanks
