How to detect out-of-sync condition

Hello list,

I recently had a user whose mailbox had gone out of sync. Webmail and client inbox totals had become vastly different and response times had become unacceptable. A doveadm force-resync fixed the problem nicely.

This will no doubt happen again as we grow the service and I would like to have some type of indication at the server level so I can run a resync on a per-user basis as required. However, I don't know what to look for. I did not see any signs of the problem on the server - but perhaps I did not know what to look for.

The only other alternative is for me to do a global resync in the cron.daily but my fear is that this won't scale well for thousands of users.

Please advise.

Thanks in advance.

There are no log entries about broken sync or something something like that?

I looked in the place where dovecot logs everything ... the maillog. I didn't see anything but the log is huge and I could have easily missed it. Is there a certain error or phrase I should look for? If so please advise.

Are you sure about maillog? I mean:

doveadm log find

gives you that file?
