    I setup ISPConfig3 as cluster on 2 servers with Failover IP. To synchronization mails I use dovecote sync.
    Problem is that, when I switch IP to backup server then all clients download again mails and have duplicate. All using POP protocol.
    Anyone known solution of this problem

    use the replication with the server-ips and not with the failover-ip and make sure, that you add the replication to the service pop

    replication use server IP, but domain use failover-ip, when thunderbird connect to backup server than get old mails as new.
    but i see that most account have fast_sync time more than 22:40:00, maybe too long sync interval is set.
    replication_full_sync_interval = 1 hours
