My setup is that I have sieve filters to put emails from mailing lists, bugzilla/github/gitlab/... and other projects into separate own mailbox, based on email headers which these services provides. So once I get email from new bugzilla, github or gitlab project, then sieve automatically creates a new mailbox for it. And this happen every time when I e.g. add a new comment to bugzilla project into which I have not commented yet. I'm having permanently opened mutt email client in tmux/screen on "All" virtual folder to see all new emails. And basically above bug cause problems in this scenario as I would not see new emails. I can re-open "All" mailbox, but first I need to know that new email was received. And for this I'm using mutt IDLing in All virtual folder. So it is like chicken and egg problem. -- Pali Rohár pali.ro...@gmail.com

I mean, workaround is for the user to just reopen the folder. I think it's not very common for this situation to happen and cause problems?

Imap clients uses either IDLE or STATUS or LIST (with STATUS) commands for checking if there is a new messages. But none of these commands reports existence of new message until that virtual folder is re-opened. -- Pali Rohár pali.ro...@gmail.com

It actually has nothing to do with IDLE specifically. It's just that the virtual storage code doesn't try to look for new folders after the virtual mailbox is opened. > To get notifications, it is needed to re-open that "All" mailbox again. Right. I don't think this is going to be fixed anytime soon. Quite a lot of effort and it can be worked around.
Bug in IDLE implementation for virtual mailbox
Hello! I found bug in Dovecot's IDLE implementation when virtual mailbox is in use. IDLE does not notify about new emails when email appears in newly created mailbox and IDLE was issued in virtual folder which matches "*" wildcard and that mailbox was created after opening virtual mailbox. This problem is present in version 2.2.34 which is available in Debian Stretch system with backports. Reproducer: 1. Create virtual "All" mailbox in Gmail-like style: $ cat All/dovecot-virtual * -Drafts -Spam -Trash ALL 2. Ensure that (real non-virtual) mailbox "Test" does not exist. 3. Create sieve rule which deliver some email to "Test" mailbox. require [ "fileinto", "mailbox" ]; ... fileinto :create "Test"; 4. Open dovecot imap connection, select virtual "All" mailbox and then enter IDLE command. 4. Send email which matches that sieve filter. Email will be processed by dovecot sieve. As "Test" mailbox does not exist, dovecot sieve would first create it and then deliver email into it. Now dovecot imap should notify IDLE client that new message into virtual "All" mailbox was delivered (as it collects emails from all - * - mailboxes). But dovecot for some unknown reason does not notify via IDLE that there is a new email. To get notifications, it is needed to re-open that "All" mailbox again. -- Pali Rohár pali.ro...@gmail.com signature.asc Description: PGP signature
