Hello Aki, Finally I am using maildir as quota backend and it works! I set the second way like it was write here http://wiki2.dovecot.org/Quota/Maildir With this method The quota can be personalized per user manually. I only have to create the file once for the new users. But I don't know if these following options in 90-quota.ext works again : quota_rule2 = Trash:storage=+100M quota_grace = 10%% I'm going to test that. Thanks a lot!
