2.3 -> 2.4 segmentation fault

Hello there,

First, thanks for the terrific job you're doing. Dovecot rocks!

I installed some time ago Dovecot on my macbook with Homebrew, that was Dovecot v2.3.18. I recently upgraded everything I installed with Homebrew to the latest which brought Dovecot to v2.4.0. I then modified my dovecot.conf file to make it work with this latest version but now, I constantly get a segmentation fault when I use the doveadm command : zsh: segmentation fault doveadm

Also, while it looks like Dovecot is listening at the specified port, my email client cannot connect anymore complaining the server refused the connection. tcp4 0 0 127.0.0.1.10143 *.* LISTEN 662

PID TTY TIME CMD 662 ?? 0:06.66 /usr/local/sbin/dovecot -F

Here is my 2.4 conf if anyone can help 🙏

dovecot_config_version = 2.4.0

log_path = /var/log/dovecot # mail_debug = yes

default_vsz_limit = 0

default_internal_user = _dovecot default_login_user = _dovenull default_internal_group = mail

mail_home=/var/mail/%{user} mail_path=sdbox:~/Mail

## this is sometimes needed # first_valid_uid = 500 last_valid_gid = 100

# if you want to use system users passdb pam { driver = pam }

userdb passwd-file { driver = passwd-file # args = blocking=no # override_fields = uid=214 gid=vmail }

protocols imap { }

service imap-login { inet_listener imap { # address = 127.0.0.1 port = 10143 } }

ssl=no # ssl_cert=</path/to/cert.pem # ssl_key=</path/to/key.pem # if you are using v2.3.0-v2.3.2.1 (or want to support non-ECC DH algorithms) # since v2.3.3 this setting has been made optional. #ssl_dh=</path/to/dh.pem

namespace inbox { inbox = yes separator = / }

Thanks a lot.
