OS: Ubuntu 22.04.1 Dovecot: 2.3.16 (7e2e900c1a)
When trying to enable the “imap_metadata” plugin, I get the following error: Plugin 'imap_metadata' not found from directory /usr/lib/dovecot/modules
I have searched high and low via Google, StackOverflow and even ChatGPT (haha) but I cannot seem to find the package that provides the plugin.
Does Dovecot have to be built from source for this plugin to be included?
Any help is appreciated.
Thank you!

Hi Aki and list,
Is there a list of which MUA's make use of IMAP METADATA ? I read the RFC and I noticed that the original author worked for Apple, but I haven't been able to determine if any Apple Mail versions support it.
Does anyone know ?
Thanks,

What I can tell is I use IMAP METADATA with roundcube as a sort of fork of Kolab project (which is using Cyrus for IMAP).
It was an attempt to wrote a plugin for thunderbird but is abandoned now.
Can be other use case I didn't know about.

This still seems to be an issue.
If I set it according to the current documentation 1, I get the following error:
Error: Plugin 'imap_metadata' not found from directory /usr/lib64/dovecot/modules
There's indeed no such .so file. It seems it's not a packaging problem either, even during compilation (with all possible ./configure flags enabled) this file is not created.
Config used:
protocol imap { mail_plugins { imap_metadata = yes } } mail_attribute { dict file { path = %{home}/attributes } }
Not urgent; I thought it's necessary for imapsieve, so I enabled "imapsieve_url". But since they are orthogonal, I can live without IMAP METADATA. It's just it doesn't work when set up according to the docs.

Hi
where in the documentation does it state that imap_metadata is a plugin?
The configuration that I saw at the link you posted is the following, i.e. not the one that you posted:
protocol imap {imap_metadata = yes}

This doesn't seem to be working with the stock docker image either.

You're right, there's an extra "mail_plugins {}" section in my snippet. I must have copied it from somewhere else and didn't notice this extra section when compared with the doc.
When I removed it and configured the rest, it works nicely.
Thank you for the hint,
Ákos
