Hi!

There is no need to put any of those settings under protocol lda {}, they can be set outside.

I'm trying to migrate my dovecot config from Fedora 42's dovecot-2.3.21.1-5.fc42.x86_64 to Fedora 43's dovecot-2.4.1-6.fc43.x86_64.

I use this command to run the LDA via deliver.sh:

---

#!/bin/sh exec /usr/libexec/dovecot/deliver -c $HOME/fetchmail/barry@barrys-emacs.org/dovecot-deliver-rc -e "$@"

It's called from a procmail script like this:

---

LDA="$HOME/fetchmail/$MAILACCOUNT/deliver.sh"

:0

• ^List-Id:.*<dovecot.dovecot.org> | $LDA -m "Others.Dovecot"

The dovecot-deliver-rc that I use for 2.3 is

log_path = /home/barry-mail/fetchmail/barry@barrys-emacs.org/logs/deliver.log

protocol lda { postmaster_address = barry@barrys-emacs.org mail_location = maildir:~/Maildir lda_mailbox_autocreate = yes }

But for 2.4 that config is invalid. For 2.4 I iterated to this:

dovecot_config_version = 2.4.0 dovecot_storage_version = 2.4.0

protocol lda { postmaster_address = barry@barrys-emacs.org lda_mailbox_autocreate = yes log_path = /home/barry-mail/fetchmail/barry@barrys-emacs.org/logs/deliver.log mail_driver = maildir mail_home = /home/barry-mail mail_path = /home/barry-mail/Maildir }

But that crashed /usr/libexec/dovecot/deliver

Is the config for 2.4 in principle correct? Where do I report the crash?
