Hi Timo, thanks for replying. My comments are inline:

However almost immediately a maildirsize folder vanished. Soon after another, then another, and now we're missing nearly 40 of them.
Maildir++ quota recalculation works like:
Go through all files and sum up their sizes. Keep track of the highest directory mtime. Once everything is calculated, again go through all directories and find the highest mtime. If the highest mtime had increased, something had changed, so delete maildirsize file.
So could it be simply that the recalculation is slow enough that the maildir changes during it and causes the file to be deleted? Another possibility is that some error happens, but then Dovecot should have logged something.
I'm not seeing anything in my logs. It's certainly possible that multiple mails are delivered during a recalculation. I'm not quite sure I understand the mtime explanation above, are you saying that if dovecot thinks that the maildirsize file is inaccurate it deletes it and goes on?
Do you keep your quota limits stored only in the maildirsize file? If not, having the files deleted shouldn't affect functionality, but of course the performance is worse.
Basically yes, we have many users with different quotas and as such we cannot use a single quota in the config file.
So, it sounds like I'm the only person who has encountered this problem? If it's really just a consequence of the maildir changing, wouldn't it be more common?
Thanks again Timo,
