[Dovecot] recalculation of maildir Quota
Hello,
I intend to use maildir Quota for measurement only, not for applying restrictions. Therefore I defined rather high values. That's working as expected. Nevertheless it's not useful, because the recalculation time is to high. This takes some minutes for my own mailaccount with 250.000 mails on a NFS storage. This would be to bad, but whilst this time, the Mailclient hangs. Probably our users woulnd't accept this. Can this be done in the background?
Furthermore I noticed that recalculation occurs after the file maildirsize gets longer than 30 lines (around 250-300 bytes) and not after 5120 bytes as the wiki states. Do I do/understand something wrong or is this a bug?
Probably a nightly cronjob, which does calculation of Maildir-size would be a more useful alternative.
Regards,
Ingo Rogalsky

"0" values would have worked as well (I think, at least works in v1.1).
Not really. Dict quota would be better for you I think, although it doesn't work very well in v1.0 either :)
Actually I did find a bug from there which could have caused this. Fixed: http://hg.dovecot.org/dovecot-1.0/rev/288fd70ac258
Hello,

This solves the issue. Thanks. Nevertheless I'm going to disable the quota plugin because of the long recalculation time and imap clients not usable during this.
But one more question: Would it be possible to disable the recalculation and do this with a nightly cronjob, which scans all mail accounts?

Depending on your needs you could always use your (Linux?) OS tools and do a du -s * or if supported du -sm * to get the size im MB. Adding a | sort -nr gives a nice list with top users of disk space first. Doing it on the machine that serves the NFS should speed it up significantly.

This would be specific to your installation, but I guess it wouldn't be too difficult to write such a script.. Anyway I won't try it. :)
