Hello dovecot!

I administer a dovecot installation with 30k users. I've got 4 dovecot directors as frontend and 10 backends.

The mailbox are now in maildir format, with maildir++ quota, on a shared netapp filer. Indexes are local on each backend.

I'm reconfiguring the quota plugin: as a first step, I want to use the clone plugin to keep a copy of the quota on a redis database. Next, I'm going to use the "count" quota backend.

I've configured without (many) issues the quota clone plugin, but now I want to force the recalculation on all the mailboxes, because I've got some (not many, but some) mailboxes that are mostly unused and are not refreshed.

At first, I was going to use "doveadm quota recalc -A", but.... I want each backend to perform the recalculation ONLY for the users he it's managing.

I can't perform "doveadm quota recalc -A" on the directors, because the quota plugin is enabled only on the backends.

I can parse the user mapping on the directors and split the calculation, one user a time, on the backends, but I feel I'm choosing a overly complicated path.

So.... which is the right way to do this?

Thanks.
