Commit: 60853

* Per-user quota configurable in UDM.
* Stores quota as (int) MB in LDAP attribute univentionMailUserQuota from univentionMail, which is attached to all users.
* Dovecot reads it directly from LDAP upon mailbox access.
* Dovecot uses maildir++ backend: writes stats into ~/Maildir/maildirsize
* Adds UCRVs mail/dovecot/quota/warning/subject and mail/dovecot/quota/warning/text/.* to configure warning mails if user gets over quota.

Read/list quotas on the command line with:
# doveadm quota get [-u <user>|-A]

r61754 | Bug #38474: updated translation in extended attribute

→ extended attribute is not removed if last dovecot app in UCS domain has been 
  uninstalled → unjoin script should check that and remove ext attr if the last
  dovecot app is uninstalled
→ see ucs_isServiceUnused in developer guide
→ REOPEN

root@slave22b:~# univention-ldapsearch -LLL uid=user1 univentionMailUserQuota mailPrimaryAddress
dn: uid=user1,cn=users,dc=nstx,dc=local
mailPrimaryAddress: mail1@nstx.local
univentionMailUserQuota: 1234
root@slave22b:~# doveadm quota get -u mail1@nstx.local
Quota name Type    Value   Limit                   %
User quota STORAGE     0 1263616                   0
User quota MESSAGE     0       -                   0

1263616 == 1234 * 1024 → OK

Functionality tested by ./40_dovecot_quota and ./41_dovecot_quota-status from ucs-test (and manually). → OK

→ works as described
