Thank you all for replies!!! Some missing infos... - As load balancer I'm using a pair of keepalived with simple setup and not the DNS - Load balancer algorithm is "Weighted Least-Connection" - About 20 domains and 3000 email - I'm monitoring my backend servers with poolmon - The backend servers are virtual machine (vmware) with datastore on "all flash" storage based

...plication you basically have two independent servers that asynchronously sync emails. While it would work with loadbalancers/keepalived/director they are not necessary. If this is the way you want to go you should configure the loadbalancer to always send the same source-ip to the same backend (ip stickyness). Mailclients do open several connections in parallel and they should see the same data. With DNS this happens automatically because ips are rotated by resolvers and the mailclient gets the same ip for all its connections. Failover is builtin as mailclients just connect to the second ip when the f...

Hi All, I have 2 test servers with the below configuration. ========================== Linux OS - Red Hat Enterprise Linux Server release 7.7 (Maipo) Dovecot version - 2.2.36 (1f10bfa63) Postfix version - 2.10.1 ========================== Trying to create High Availability. I have added both of the above servers behind a F5 load balancer. I have got a Load Balancer FQDN

...ed to server A sometimes to server B. So you just see the mails on the respective server. This is very bad. Your Mailclient is probably syncing and deleting emails everytime the connection is moved to the other server. As I suggested in the other thread you should at least configure some kind of ip stickyness when using a loadbalancer, so that your mailclient reaches the same backend. The purpose of replication is that two servers, operating independently, have the same dataset. Your servers seem to have completely distinct datasets, which indicates replication is not working. Did you configure replica...

hello list, I am attempting to load balance SSL web servers using haproxy on centos 5.7. I am using HA-Proxy version 1.4.18 Here is the stanza in the config regarding SSL: listen https 192.168.1.200:443 mode tcp balance roundrobin option forwardfor except 192.168.1.200 option redispatch maxconn 10000 reqadd X-Forwarded-Proto:\ https

In my setup the load balancers do exactly this, and the director map the same username/email (not the same source IP) to the same backend server.
