The first step is to log into the podman. To enter, we use:
/usr/local/bin/runagent -m mail1
Further documentation:
# print the config values that differ from Dovecot defaults
# WARNING! changing one of them may be dangerous!
podman exec -ti dovecot doveconf -n
# start the editor
podman exec -ti dovecot vi /etc/dovecot/local.conf.d/myoverride.conf
systemctl --user reload dovecot
And at the end the config. Taken from here and finalized with a file.
Also the port must be opened on the firewall in the actual machine! I don’t know which protocol is needed, so I opened both. The instructions require port 4092.
firewall-cmd --add-port=4092/tcp
firewall-cmd --add-port=4092/udp
It is necessary to specify IP address for synchronization!!!
mail_replica = tcp:195.888.888.888:4092
# cat conf.d/10-replicator.conf
mail_plugins = $mail_plugins notify replication
# Replicator process should be started at startup, so it can start replicating users immediately
service replicator {
process_min_avail = 1
# Enable doveadm replicator commands
unix_listener replicator-doveadm {
user = vmail
group = vmail
mode = 0660
}
}
service aggregator {
fifo_listener replication-notify-fifo {
user = vmail
}
unix_listener replication-notify {
user = vmail
}
