Hi people,

I am setting up replication between two servers. The installation of the servers was done using ispconfig and the operating system is debian 10. The problem is that after following the guide for this configuration, https://wiki.dovecot.org/Replication, when I start the server, replication does not start. I have also checked, via tcpdump, on the port associated with doveadm. If I force it with the command "doveadm -D sync -u user @ domain -d -N -l 30 -U" the replication happens, but it is not updating when the user receives emails on server01.

At this time server02 will not receive emails (via postfix), and will also not have users accessing via pop3 or imap, but I have the idea of configuring so that both servers have these services working.

The configuration of the servers is below:
