Re: Public NameSpace using sdbox with INDEXPVT for per-user-seen flags does not take into account the dovecot-shared file flag

29 Mar 2021 · *dovecot-shared*

      Thank you Aki, for your quick response.
*dovecot-shared* file flag should actually enable the *INDEXPVT *setting
in the NameSpace for each mailbox it has been created in, as it did for
INDEX setting.
Below folows the output of the dovecot -n command:

Is it a bug of some kind?

Dear Timo,
we have successfully used dovecot-shared file flag in MaildirPublicNameSpaces with private index files, to have per-user-seen flags for some but not all mailboxesunder public folders.
This was actually done on older dovecot versions (i.e dovecot v2.2.33.2) , using a location setting in dovecot.conf like:
location = maildir:/var/vmail/PublicFolders:LAYOUT=fs:DIRNAME=privDirMailFolder:INDEX=~/Maildir/public
We try to use similar location setting using sdbox storage in dovecot v2.3.4.1, like below:
location = sdbox:/var/vmail/PublicFolders:LAYOUT=fs:DIRNAME=dbox-MailFolder:INDEXPVT=~/Maildir/public
but the dovecot-sharedfile flag seems to be ignored.
As a result all mailboxes under public folders use the per-user-seen flags setting as set in the location setting, regardless of the existence of the dovecot-shared file flag or not.
Is there any setting to use so that only some mailboxes under public folders use per-user-seen flags?
Thank you in advance for your support,
Panos Fafakos.
Hi Panos,
INDEXPVT is a namespace level setting, not per-folder setting. I cannot see any "dovecot-sharedfile" flag, maybe provide doveconf -n?
