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

Error: Corrupted index cache file/home/xxxxxx/mail/.imap/sent-mail/dovecot.index.cache: Broken virtual size for mail UID 67: 1 Time(s) Error: FETCH [] for mailbox ~/mail/sent-mail UID 67 got too little data: 6203 vs 7478: 1 Time(s)

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.
