2.3 -> 2.4 migration problem(s)

30 Apr 2025


      Recently in debian sid version 2.4 appeared and I tried to migrate.
it (mostly working) but
Neither dovecot-lda nor doveadm does not see current system user
context i.e.
--8<---------------cut here---------------start------------->8---
%doveadm mailbox list

Fatal: One of -u, -F, -A or --no-userdb-lookup must be provided
--8<---------------cut here---------------end--------------->8---
from lda logs
--8<---------------cut here---------------start------------->8---
Fatal: Namespace root: mail_storage settings: Failed to parse configuration: Invalid setting mail_path=~/Mail/0/: mail_path setting used home directory (~/) but there is no mail_home and userdb didn't return it
--8<---------------cut here---------------end--------------->8---
for dovecot-lda
setting "mail_home = /home/%{user|username}"
helped but still ...
doveadm mailbox list -u kjonca
and "-d" option helped in both cases
Moreover I found that doveadm does not work when dovecot is stoped (but
used to work in 2.3.x)
Another thing is:
--8<---------------cut here---------------start------------->8---
deliver_log_format = msgid=%m: %$
--8<---------------cut here---------------end--------------->8---
in 2.3.x configuration it created line like this:
--8<---------------cut here---------------start------------->8---
2025-04-27T02:08:31.925845+02:00 alfa dovecot: LDA(kjonca): sieve: msgid=<fd248603-b186-4ee2-9e76-b9b9c0fe7a87@alfa>: fileinto action: stored mail into mailbox 'RSS'
--8<---------------cut here---------------end--------------->8---
but now it does not work (what is strange I cannot find %$ description
and %m is described as "mechanism" not message id ...)
So how can I have old loggin and authentication mechanisms?
