How to use virtual "All" and "Flagged" mailbox?
by A B 01 Feb '22

01 Feb '22

Hello, I'm trying to use the virtual "All" and "Flagged" mailboxes as described in 15-mailboxes.conf. The information here ( https://doc.dovecot.org/configuration_manual/virtual_plugin/) doesn't really touch on how to actually interact with the virtual mailboxes. My presumption is that when I mark an email message in the Inbox as FLAGGED (and I can confirm the \Flagged flag has been set) then I should then be able to either (1) see a copy of that message in the virtual.Flagged folder, or (2) when I use an imap command to get the message nums or whatever from the virtual.Flagged folder/mailbox, it should return the message that is flagged in the inbox as a result. Additionally, I'm presuming that for each new user that automatically gets added, I would have to create my own script that would add the dovecot-virtual file, dovecot doesn't do that on its own. When I view the user's directory I see these folders were created: --- [snippet] drwxrwx---. 5 vmail vmail 135 Jan 25 17:01 .virtual.All/ drwxrwx---. 5 vmail vmail 158 Jan 25 17:14 .virtual.Flagged/ [.virtual.Flagged]# ll total 20 drwxrwx---. 5 vmail vmail 158 Jan 25 17:14 ./ drwxrwx---. 20 vmail vmail 4096 Jan 25 17:33 ../ drwxrwx---. 2 vmail vmail 6 Jan 25 16:58 cur/ -rw-rw----. 1 vmail vmail 868 Jan 25 16:58 dovecot.index.cache -rw-rw----. 1 vmail vmail 384 Jan 25 17:01 dovecot.index.log -rw-rw----. 1 vmail vmail 51 Jan 25 17:01 dovecot-uidlist -rw-r--r--. 1 vmail vmail 8 Jan 25 17:14 dovecot-virtual -rw-rw----. 1 vmail vmail 0 Jan 25 16:58 maildirfolder drwxrwx---. 2 vmail vmail 6 Jan 25 16:58 new/ drwxrwx---. 2 vmail vmail 6 Jan 25 16:58 tmp [.virtual.Flagged]# cat dovecot-virtual * flagged --- Side note: This set-up uses the php-imap library to interact with Dovecot. Any help, or just concept of how the virtual/All virtual/Flagged directories work would be really appreciated.

Quota: read how much diskspace is available?
by Hans van Zijst 01 Feb '22

01 Feb '22

Hi, I've been trying to get domain quotas to work for a while, but to no avail so far. Is there a way to let Dovecot simply check how much space is still available in a directory? I'm using GlusterFS as my mailstore, so I can configure quotas per directory. All I need is a way to let Dovecot check quota in a way like "df /var/vmail/<domain>". Kind regards, Hans
