So each process has one inotify instance with just two watches. I was

under the impression that subfolders were also watched, but after testing a bit, it seems to not be true. Only the SELECTed box is watched, right?

Right.

Is there some way to have clients watch all folders? Server-side filtering

loses a bit of its value when you are not notified of the new mail.

Clients typically issue STATUS command for all mailboxes every n minutes. I've been thinking about having Dovecot issue STATUS events automatically when mailboxes change, but last I checked most clients just ignored them. There exists also a draft of a new IMAP extension where clients can ask for those STATUS events from specified mailboxes.

I guess you're using a single UID for all users? In that case the
upper limits are:

 - max_user_instances = max_mail_processes setting
 - max_user_watches = max_mail_processes setting*2

I think max_user_watches is per instance, so should that just be 2?

So it seems.
