<div name="quoted-content">

<p>I am pretty sure Synoptic/INBOX/Archives will not be same as INBOX/Archives.</p>
<p>a SELECT Synoptic/INBOX/Archives<br/>
a NO Mailbox doesn't exist: Synoptic/INBOX/Archives (0.001 + 0.000 secs).<br/>

<p>a SELECT INBOX/Archives<br/>
* FLAGS (\Answered \Flagged \Deleted \Seen \Draft)<br/>
* OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted.<br/>
* 45 EXISTS</p>
<p>So as you can see, specifying 'INBOX/Archives' under 'Synoptic' namespace means it will not be the same as INBOX/Archives. It is a separate mailbox, and the only way it can work is if you have INBOX/Archives/dovecot-virtual file which specifies that it reads & writes to INBOX/Archives. This is not the way to make some kind of fancy aliasing.</p>
<p>I took a stab at reproducing your issue, but so far no luck. I have to try including the Archiv namespace as well.</p>

Yes, i have for all of them similar Folders and Configurations. But i thought, it was to much to send you, because, they all are similar.<br/>
<br/>
There is one Namespace "Real" with according Folder in /var/mail/real.<br/>
This Namespace is hidden to the User. It is used to "prepare" the views to the emails. All Emails, only all emails from the last month, halfyear, year, 2 years and so on. The Archive in the dovecot-virtual config in "Archiv" is a separate Namespace. (look below)<br/>
<br/>
/var/mail/real: # l<br/>
insgesamt 0<br/>
drwxr-sr-x 1 vmail vmail 30 Jul 12 17:47 Alle<br/>
drwxr-sr-x 1 vmail vmail 30 Jul 10 00:06 Archiv<br/>
drwxr-sr-x 1 vmail vmail 30 Jul 10 00:06 Archiv_zweijahr<br/>
-rw-r--r-- 1 vmail vmail 0 Nov 27 2017 dovecot-acl-list<br/>
drwxr-sr-x 1 vmail vmail 30 Jul 12 11:06 dreijahr<br/>
drwxr-sr-x 1 vmail vmail 30 Jul 12 11:06 einjahr<br/>
drwxr-sr-x 1 vmail vmail 30 Jul 10 00:06 einmonat<br/>
drwxr-sr-x 1 vmail vmail 30 Jul 12 17:46 halbjahr<br/>
drwxr-sr-x 1 vmail vmail 30 Jul 12 11:06 zweijahr<br/>
drwxr-sr-x 1 vmail vmail 30 Jul 10 00:06 zweimonat<br/>
<br/>
For example:<br/>
/var/mail/real: # cat Alle/dovecot-virtual<br/>
!INBOX<br/>
INBOX/*<br/>
-INBOX/Trash<br/>
-INBOX/Trash/*<br/>
-INBOX/Archives<br/>

-INBOX/Drafts<br/>
-INBOX/Drafts/*<br/>
-INBOX/Junk<br/>
-INBOX/Junk/*<br/>
-INBOX/SYSTEM<br/>
-INBOX/SYSTEM/*<br/>
all<br/>
<br/>
The "All-Mailbox" for only one year:<br/>
/var/mail/real: # cat einjahr/dovecot-virtual<br/>
!Real/Alle<br/>
all younger 31536000<br/>
<br/>
The others "zweijahr", "halbjahr" and so on keep the same definition, but with other count of seconds... this is for playing around, which is the best period to hold in the "AKTUELLE" Mailbox in Synoptic. And to choose in Thunderbird or other Mailclients, for faster syncing or more emails.<br/>
<br/>
and the Archiv:<br/>
/var/mail/real: # cat Archiv/dovecot-virtual<br/>
Archiv/*<br/>
all<br/>
<br/>
And now the other Folder /var/mail/virtual, which contains the Namespace "SYNOPTIC". Here i collect different Views for my emails. This Namespace is shown to the User, and i can subscribe them in the MUA.<br/>
<br/>
/var/mail/virtual: # cat AKTUELL/dovecot-virtual<br/>
!Real/halbjahr<br/>
all<br/>
<br/>
/var/mail/virtual: # cat ARCHIV/dovecot-virtual<br/>
Archiv<br/>
Archiv/*<br/>
all younger 1261440000<br/>
<br/>
/var/mail/virtual: # cat Ungelesene/dovecot-virtual<br/>
Real/Alle<br/>
unseen<br/>
<br/>
/var/mail/virtual: # cat Sent/dovecot-virtual<br/>
!INBOX/Sent<br/>
INBOX/Sent/*<br/>
all<br/>
<br/>
and the Namespace "Archive" is located in<br/>
/var/mail/archiv<br/>
and contains all archieved emails. (There are really a lot Emails).<br/>
I declare this Namespace as "Special Folder", so Thunderbird picks it up as the Archive-Folder for automatic archieving old emails.<br/>
<br/>
The thing is, I get the error on the "Alle", "Send", "ungelesene"... Mailboxes. The Archiv-Mailbox is working correctly!<br/>
<br/>
Another funny thing is... I got this error on older versions and also on version 2.4 (=master in git). But not all the time.<br/>
Some day it worked without error... It worked until i deleted the whole index-directories a few days ago... then i got the error. Without changing the config!!<br/>
<br/>
Uhmm... Yes, there is this Synoptic/INBOX/Archives Mailbox. This is for a special Mailclient "K9Mail" (on Android). Because i used there only the Synoptic-Namespace. And K9Mail created itself an own Archive-Folder, if there is no one below INBOX. With this solution, K9Mail shows the same Archive as Thunderbird shows ist as Special folder.<br/>
<br/>
<br/>
The Gmail-App handles different Namespaces at the same time, but cannot handle different Identities.<br/>
K9Mail can handle different Identities (for Alias-Emailadresses) for the same Account, but only one Namespace...<br/>

<b>Betreff:</b> Re: Panic: Leaked view for index - virtual mailbox</div>
<div>Hi!<br/>
<br/>
Was looking at your config and I am puzzled why you are adding<br/>
<br/>
mailbox INBOX/Archives {<br/>
auto = no<br/>
special_use = \Archive<br/>
}<br/>
<br/>
under namespace 'Synoptic'? Do you actually have a virtual folder config<br/>
for all those folders? You can't just "move" folders into a namespace by<br/>
declaring them there, those become Synoptic/INBOX/Archives, and require<br/>
a dovecot-virtual file to work.<br/>
<br/>
If the only mailbox in Synoptic, that has a dovecot-virtual file is<br/>
'AKTUELL', you should remove all folders that do not have a<br/>
dovecot-virtual file under /var/mail/virtual.<br/>
<br/>
