If you are running your container as root. You will not have the issues I encountered. Dovecot is dropping to the 'dovecot' and 'dovenull'(?) when needed, this is fine.

PS. I would not recommend using internal logging, use something like this to log to the host or remote syslog. docker run -v /dev/log:/dev/log -it dovecot-proxy

Hi Marc,

I can see the processes are running as a root in container environment. Do you think that still have issues ? Here is the processes running inside container:

bash-4.2# ps -ef UID PID PPID C STIME TTY TIME CMD root 1 0 0 Dec27 ? 00:00:00 /bin/bash /bootstrap.sh root 7 1 0 Dec27 ? 00:00:00 /usr/sbin/dovecot -F -c /etc/dovecot/director.conf root 8 1 0 Dec27 ? 00:00:00 /usr/sbin/dovecot -F root 9 1 0 Dec27 ? 00:00:00 sleep 36000d dovecot 10 8 0 Dec27 ? 00:00:00 dovecot-Dovecot/anvil dovecot 14 7 0 Dec27 ? 00:00:00 dovecot-Director/anvil root 267 8 0 Dec27 ? 00:00:00 dovecot-Dovecot/log root 269 8 0 Dec27 ? 00:00:08 dovecot-Dovecot/config root 281 7 0 Dec27 ? 00:00:00 dovecot-Director/log root 283 7 0 Dec27 ? 00:00:00 dovecot-Director/config

Thanks & Regards, Naveen

I have noticed several issues with dovecot, trying to run it 

without root. Which is preferable in any container environment. Maybe you would like me to document these somewhere? So at some point they can be applied.

Hi, I can see those values correctly with the doveconf -nc command. 

Here is the part of output:

bash-4.2# doveconf -nc /etc/dovecot/director.conf # 2.2.36 

(1f10bfa63): /etc/dovecot/director.conf # OS: Linux 4.1.12-112.14.11.el7uek.x86_64 x86_64 Red Hat Enterprise Linux Server release 7.7 (Maipo) # Hostname: 69b492645b56 auth_debug = yes auth_default_realm = xxxxxxxxxxxxxxxx

auth_verbose = yes base_dir = /var/run/dovecot_director 

debug_log_path = $log_path director_mail_servers = xxxxxxxxxxxxxxxxxx director_servers = xxxxxxxxxxxxxxxxxxxx disable_plaintext_auth = no first_valid_uid = 1000 hostname = xxxxxxxxxxxxxxxxxxxx info_log_path = $log_path instance_name = Director lmtp_proxy = yes log_path = /dovecot.log login_log_format_elements = user=<%u> method=%m rip=%r lip=%l mpid=%e %c home=%h

        Can you check with `doveconf -nc /path/to/director.conf` 

that the values are actually set correctly?

                The conf.d files are not included. I have added  

!include conf.d/*.conf to director.conf and reloaded the dovecot and director services.

                conf.d/10-logging also has the following lines: 

                log_path = /dovecot.log 
                info_log_path = $log_path

                The /dovecot.log file still shows empty.  Nothing 

is being logged to that file.

                        Do you have !include or !try_include in 

director.conf? The conf.d files are not included otherwise.

an issue that we are running into when we are trying to run Dovecot in Docker container.
