Sieve is not working. Before the upgrade to Debian 13 from Debian 12,
sieve was working fine. Mail was being moved to different folders
according to the rules. The rules have not changed, and have been
revalidated subsequent to the move. Despite logging, there is no sign that
sieve is ever running, although test mail messages qualify for being
moved.
The output from doveconf -n is attached. The only mention of sieve in
/var/log/mail.log is:
Sep 28 04:28:02 mx dovecot[1861243]: master: Dovecot v2.4.1-4 (7d8c0e5759)
starting up for imap, lmtp, sieve, pop3 (core dumps disabled)
The only recent mention of sieve in any log (apart from dpkg) is:
mail.log:Sep 28 04:28:02 mx dovecot[1861243]: master: Dovecot v2.4.1-4
(7d8c0e5759) starting up for imap, lmtp, sieve, pop3 (core dumps disabled)
Older logs show testing actions, but no actual sieve operations.
managesieve is working.

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.
