Hi Aki!

The config is in the attachment.

The output from gdb is this:

And i have a complex setup for virtual mailboxes...

Hi Aki!

The config is in the attachment.

The output from gdb is this:

And i have a complex setup for virtual mailboxes...

And for Real/halbjahr it is:

Panic: Leaked view for index - virtual mailbox

Hi!

Was looking at your config and I am puzzled why you are adding

? mailbox INBOX/Archives {
??? auto = no
??? special_use = \Archive
? }

under namespace 'Synoptic'? Do you actually have a virtual folder config
for all those folders? You can't just "move" folders into a
namespace by
declaring them there, those become Synoptic/INBOX/Archives, and require
a dovecot-virtual file to work.

If the only mailbox in Synoptic, that has a dovecot-virtual file is
'AKTUELL', you should remove all folders that do not have a
dovecot-virtual file under /var/mail/virtual.

Aki
