Plugin to cleanup/remove unused user defined keywords(IMAP PERMANENTFLAGS) possible ?

I found a reference to a similar issues here: https://www.dovecot.org/list/dovecot/2010-March/047925.html I know IMAP rfc say nothing about removing the keywords/PERMANENTFLAGS (they can only be added https://www.rfc-editor.org/rfc/rfc3501.html#page-64) , therefore I wonder if it is possible to create a Dovecot plugin to accomplish this task ? Technically it is possible to do now via the following steps: 1. Ensure the "unwanted" user defined keyword/flag is remove from all messages in a folder (Folder A) 2. Create a temporary folder (Folder A_temp) 3. Move all messages from Folder A -> Folder A_temp 4. Delete Folder A 5. Rename Folder A_temp -> Folder A As you can see this highly inefficient and awkward and even if the unwanted keyword does NOT appear in Folder A anymore , it still can be found in '~/Maildir/dovecot-keywords' file Alternatively, if it is hard to create a plugin that would remove the keyword for good, would something like this be easier: 1. Define a list of "allowed" user defined keywords 1a. Perhaps this list can be defined via METADATA extension on per folder basis 2. Reject(or discard) "not allowed" keyword sent via the +FLAGS / +FLAGS.SILENT commands Any helpful plugin example or code references would be greatly appreciated. Thank you very much, Sergey Mosin

Hi Is there a contact address for operation of this list server. I have some observations regarding ARC signing to share. Regards Paul

Compression: all or nothing?
by Alex King 02 Oct '23

02 Oct '23

Using 2.3.13 (89f716dc2) (debian package), with mdbox storage. I considering adding the zlib plugin. I understand that reading mail can cope with either compressed or uncompressed mailboxes. I'm wondering if I can leave the main storage uncompressed, while having the alternate storage compressed. There does not seem to be a way to configure this, from https://doc.dovecot.org/settings/plugin/zlib-plugin/ it seems compression (on saving emails) is an all-or-nothing option? Can I leave zlib_save unset in my main configuration, and have doveadm use some alternate configuration with zlib_save set? It doesn't look hopeful because I don't see the ability to use a different config at https://wiki.dovecot.org/Tools/Doveadm/Altmove. Perhaps I would need multiple copies of the daemon running? Or is it better just to compress everything? I plan to store older mails (perhaps 3months+) in the alternative storage, and was thinking it would be nice to have those compressed, while I don't need to compress the main store. Any feedback welcome. Thanks, Alex

Re: Changed separator, sub folders not showing new e-mail

I found the answer here: https://apple.stackexchange.com/questions/441313/no-mailbox-doesnt-exist-se… Apparently on Mac one needs to update the separator on a file, since it doesn’t seem that the Mail.app does it for itself. On the iPhone it happened automatically. Best, Francis

Changed separator, sub folders not showing new e-mail
by Francis Augusto Medeiros-Logeay 02 Oct '23

Hi, I recently changed the mailbox separator from '.' to '/' so that I could have shared mailboxes working. However, while the mailboxes show fine on Roundcube and on other web-based e-mail clients, on the Mail.app on my Mac I don't get newer messages on those sub folders. For example, I have a subfolder Test. Mails filtered to be dropped there, show fine. But I have one called Lists, with a sub folder called "Dovecot". I can't read mails that are under "Lists/Dovecot". Can anyone help? Best, Francis -- Francis Augusto Medeiros-Logeay Oslo, Norway
