Hi, I am new to Dovecot and Debian, but I seem to have got Dovecot up and running with local delivery and then switched to LMTP. I am running Debian 12.7 and Webmin 2.202 to try and get things running, but I've had to tweak files. Also Webmin did not install dovecot-lmtpd, dovecot-sieve or dovecot-managesieved, so I did that manually. I have tried following the configuration guide from Dovecot (but there seems to be little there) and other sources I've found on the internet, but there is nothing I have found to get sieve listening on port 4190 when checked with ss.
My Dovecot config from dovecot -n is:
# 2.3.19.1 (9b53102964): /etc/dovecot/dovecot.conf
# Pigeonhole version 0.5.19 (4eae2f79)
# OS: Linux 6.1.0-26-amd64 x86_64 Debian 12.7
# Hostname: my.fqdn

Dovecot packages installed from the Debian repos are:

dovecot-sieve/stable,stable-security,now 1:2.3.19.1+dfsg1-2.1+deb12u1 amd64 [installed]
Ultimately I intend to run manage sieve from Roundcube which I have already got running, or I may try a Thunderbird addon.
Can anyone give me some pointers, please?
