Under the hood, IDs are what the filesystem use to keep track of projects, the config files are merely a convenience to translate ids into names (with one exception). > 2. i've seen that if I remove the directory /var/mail/domain1.tld, the > related project is still showing in the quota report, but if I > recreate the directory, the quota is not honored anymore. You remove the directory, you also remove all the metadata associated with that, which include project quota flags. Once you create the directory again, you need to set it up quotas for that directory again. > 3. how can I delete a single project if not needed anymore? You need to clear it by using 'project -C' argument, but to do so, the project must be listed in the config files (the exception I mentioned above). > 4. can I use multiple quotas for the same path, in example > /domain1.tld 1GB, /domain1.tld/mailbox1 500MB /domain1.tld/mailbox2 > 500MB (allowing, in example, 2 different mailboxes, 500MB each and > still 1GB from the parent direcory) I believe you mean multiple quotas for the same mount point? All the examples you gave here are different paths, if so, then yes, you can use different project quotas for different directories under the same mount point. Carlos
