I have a question about the quota-system in iREdmail.
== Observation ==
When I create a new mail-domain with an unlimited quota, I'm also able to create mailusers under that domain with an unlimited quota; that's expected.
When I change the quota for that domain from unlimited to a fix value, the previously created, the unlimited mailusers are not effected. When I now change something of the unlimited mailuser, even if it's unrelated to their quota, like the phone-number or timezone, that user gets all the remaining space of that domain-quota.
When I create a new user under a domain with a domain-quota, that newly created mailuser takes all the remaining space of the domain-quota, even when the quota-field left empty or set to zero ("0").
== My Problem ==
I have a domain with a fixed quota of 25GB and an amount of user that vary. Therefore giving every current user (50 right now) a fixed quota, would prevent me from creating new users if necessary, unless I change the quota of some users manually to create free quota-space.
My second problem is, that some mailusers need mailboxes up to 3GB, while others barely use them and only have mailboxes up to 10MB. Unfortunately I can't tell when which users needs a bigger mailbox-quota or when a new user should be created, since that work should be done by the domainadmin (I'm a global admin).
== My Wish ==
Therefore I wanted to know if it's possible to create a domain with a fixed quota but an "unlimited" amount of users with an unlimited user-quota, where the limiting factor is solely the domainquota, so I don't have to adjust user-quotas manually, when something is changing (number of users and /or their size of mailboxes).
Hopefully my question is comprehensible.
