Shared folders and quota

9 Feb 2018


      Hi all,
we are able to observe a very strange behaviour:
User A wants to copy a mail to a shared mailbox of user B. This works like a
charme if the quota of user A is lower than the used space of user B. But is the
used space of user B higher than the quota size of User A, "User A" is not longer
able to copy the message to the shared folder of user B. His IMAP Client says
something like "NO OVERQUOTA".
# doveadm quota get -u UserA
Quota name   Type    Value Limit    %
User quota   STORAGE 20085 25600   78
User quota   MESSAGE    68     -    0
# doveadm quota get -u UserB
Quota name   Type    Value  Limit   %
User quota   STORAGE 39963 122880  32
User quota   MESSAGE   160      -   0
Is this a known behaviour of dovecot? Is there a way to "disable" quota-handling
for shared folders?
