Problem with replication between two servers (ispconfig)

12 May 2021


      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:
root@server01:~# doveconf -n
# 2.3.4.1 (f79e8e7e4): /etc/dovecot/dovecot.conf
# Pigeonhole version 0.5.4 ()
