Dear all,
I guess I found a bug.
I'm currently testing a migration of my Debian based dovecot bare metal
installation from 2.3.19 --> 2.4.1
I'm using shared mailboxes.
My understanding from the documentation is: "Quota plugin considers
shared namespaces against owner's quota" and "The quota limits are also
taken from the userdb."
The following setup leads to a "Panic: file quota.c":
* Quota is defined per-user and defined in a MySQL Database (and looked
up as part of userdb)
* User A shares directory "Inbox/teilemich" with user B.
* User B has full access rights (details see below)
* User A has a quota of 100MB - currently using 60%
* User B has a quota of 4GB - currently using 550MB
* User A puts mail xyz in the shared directory --> works
* User B puts mail abc in the shared directory --> error message (see
below) and mail is not stored.
Defining the following not-overwritable global quota > 550 MB eliminates
the error message. Defining a global quota < 550 MB still leads to the
error message.
quota "User quota" {
storage_size = 560M
storage_grace = 10M
}
Defining an overwritable global quota that is > 550 MB still leads to
the error message.
quota_storage_size = 560M
quota "User quota" {
storage_grace = 10M
}
Can you please check, if this is a bug?
If you need some details I'm happy to provide it.
Also - I would be very grateful for a workaround / fix.
Thanks for all the effort & Best regards,
Christopher
