Thanks. The contents of 20-lmtp.conf (with comments removed):
protocol lmtp {
mail_plugins {
sieve = yes
}
auth_username_format = %{user}
}
Is that what you meant?
From logwatch:
config: Fatal: Plugin 'sieve_lmtpsieve' not found from directory
/usr/lib/dovecot/modules/sieve: 10 Time(s)
Referenced directory:
[1]root@mx:/etc/dovecot/conf.d# ls -l /usr/lib/dovecot/modules/sieve
total 136
-rw-r--r-- 1 root root 71848 Jun 18 15:01

-rw-r--r-- 1 root root 47192 Jun 18 15:01
lib90_sieve_extprograms_plugin.so
-rw-r--r-- 1 root root 14424 Jun 18 15:01 lib90_sieve_imapsieve_plugin.so
I don't see anything to do with lmtp there (which may make sense), but
don't know how I would add anything.

But the messages in the log saying the plugin sieve_lmtpsieve is missing seems
fundamental and relevant. I can't find anything called that in the Debian
repository. How is it installed? Or am I doing something fundamentally wrong?

Feels like you asked an LLM. Anyways this should work
protocol lmtp {
mail_plugins {
sieve = yes
}
}
