Re: lost quota root

[Michael Menge <michael.menge@xxxxxxxxxxxxxxxxxxxx>]

Hi,

diging into this I found that the "quota -f user" tiggert a
bug in the quota legacy db. Only a small part of the quotaroots
where found and the quotaroot for all other mailboxes was set to none

See https://bugzilla.cyrusimap.org/show_bug.cgi?id=3735 for details.
