What exactly is not working? Can you attach doveconf -n output and, if necessary, log entries?

Is there any answer to my problem with sieve not working with Dovecot
2.4.1 from Debian 13?
I have twice been told that it will work if my configuration includes:
protocol lmtp { mail_plugins {
sieve = yes }
}}
But that has always been present. There is one and only one entry for
protocol lmtp.
It still makes no sense to me that logs complain about a non-existent
module - it is not referenced anywhere in the configuration.
Is there any solution or must I downgrade to Dovecot 2.3 to have a
properly working system?
Best regards, Martin

Debian dovecot 2.4.1 /etc/dovecot/conf.d/20-lmtp.conf has the lines
"mail_plugin" and "sieve = yes" commented-out by default.
dovecot.conf should have a line at the bottom "!include_try
local.conf". Uncomment this line. Place the above lines in
/etc/dovecot/local.conf.
Always run doveconf for syntax correctness. Invalid syntax in
dovecot.conf will log.
FYI: Many dovecot sections and variables can be overridden by later
occurrences, but some are not. I run dovecot on Debian. Debian
dovecot.conf concatenates conf.d/* into one file. The "passwd pam" {
... } cannot be overridden.
Always run doveconf to see how many passwd and userdb sections
show-up.
Pro-tip: Remove the include conf.d/* lines in dovecot.conf. and just
manually concatenate the conf.d/* lines in dovecot.conf. Everything
in one place and your configuration won't break when an upgrade
occurs. Do you want to have many changes in multiple files under
conf.d/*?
I filed a security bug with dovecot 2.4.1. I have not heard back. I
read that I am supposed to file this kind of bug with the Linux
Distro, Debian. The bug is 2.4.1 will give the same uid/gid to any
account after the first authentication. Everyone else gets the same
uid/gid and all clients start downloading the folders/email of this
first uid/gid.
2.4.1 is not production ready.
Stay with 2.3.+ until it is ready.
Such bug has not been reported to us yet, but it sounds overly broad.
Lets see if someone sends this to our way as well.
