Hi,
since one or two month I have a problem with Dovecot not updating the read-flag on mails using IMAP. I receive new mails, but when reading, they still unread on other devices (but shown as read on the first device).
When I remember correct, this problem doesn't come with an update of dovecot, but just occured at some time. But I've updated dovecot since then a few times.
Whenever a client connects to dovecot I get an panic in the log. I therefore added a log file and my dovecot configuration (is this fine or does it need to be in the mail body?). There are system information in the output of dovecot -n; the filesystem dovecot is running on is ext4.
I hope I provided all information needed and seeing forward to get a hint what the problem might be.
