dovecot - Apr 2013 - dsync replication: quota counted twice

Hi

I enabled quota + warnings in my replication test setup and now
whenever a mail gets delivered the quota is counted twice (probably due
to both servers using the same mysql quota backend) and quota warnings
are fired too early. After a doveadm quota recalc -u <username> the
quota is correct again. How do I make dovecot only count the quota on
the server where the mail was added originally? 

dovecot -n is the same as in my previous message to the list today
http://www.dovecot.org/list/dovecot/2013-April/089558.html (thanks Timo
for the hint in this thread btw, changing the permissions made the
errors go away)

Thanks
Oli

Yes. Dovecot doesn't know that they are the same quota backend.

There's no way to make quota work reliably that way. You need to use
different quota backends. Either two mysql databases (or tables), or the other
Dovecot could simply be using a dict file quota.
