Hello. How to configure the replication of mail servers in the new version? I do not understand. Do you need to do this through Relay?
I have configured Relay but on the slave server I get the following text:

Whatās wrong?
The mail2 server is the main server,
server mail1 is the slave.
Relay is configured on both
I donāt know if I understood correctly but if itās about using failover servers for sending then you just need the right MX records in DNS for your servers, see also Mail ā NS8 documentation and MX record - Wikipedia
Iād like to make two mail servers that will replicated between them. That is, if the first mail server goes down, the second one will have a complete or nearly complete copy of the messages.
I realized that dovecot needs to be configured.
I ran the command:
podman exec -ti dovecot doveconf -n
It didnāt work. I need to run the command:
runagent -m mail1
But it doesnāt work either!
What could be the reason?
Iām getting an error:
No such file or directory: '/home/user/.config/state/agent.env'
Hereās how to customize dovecot:
Enter the app environment:
runagent -m mail1
Show the dovecot config:
podman exec -ti dovecot doveconf -n
Edit the configuration:
podman exec -ti postfix vi /etc/postfix/main.cf.d/myoverride.cf
Restart the service:
systemctl --user reload postfix
It should be something like /home/<app_instance_name>/.config/state/...
I have an error:
bash: runagent: command not found
I just donāt understand how to get this up and running! I looked it up in the manuals. Thereās no such thing. What kind of magic is this?
I couldnāt find instructions on the nethserver command line logic. I realized that nethserver works in podman I found the containers and logged into them, but nothing works there either. Maybe this is beyond the scope of nethserver but really not clear.
More or lessā¦ runagent is a wrapper command located at /usr/local/bin/runagent
, IIRC it requires to be root (executed on CLI without needing to access podman container beforehand). Used to access, inspect and modify rootless containers.
Thank you very much for your reply. It is not in any manual. If it wasnāt for you, I wouldnāt have figured out how to do it! Now I have found the entry point from which there are manuals!
P.s. In the end, the entry point looks like this:
/usr/local/bin/runagent -m mail1
Where the number may not be 1. The digit must be viewed in the web console. I have uninstalled and reinstalled the mail application many times, so I have it as mail15.
one way to edit files inside container:
