Round-robin DNS last I checked can be fraught with issues. While doing something else I came up with this idea: Clients --> Load Balancer(HAProxy) --> Dovecot Proxy(DP) --> Dovecot Director(DD) --> MS1 / MS2. When DP checks say user100 it'll find a host=DD-POD1 that returns two IPs, those of the two DD that sit in front of POD1. This DD pair is the only pair in the ring and only responsible for POD1. Another pair will handle POD2. When DD looks up the host value for a user it'll find the same name, but the IPs returned will be different. Instead ha...

I'm trying to determine which dovecot components to use and how to order them in the network path from client to mail store. If I have say 1,000 users, all stored in MySQL (or LDAP) and have 4 mail stores, configured into 2, 2 node pods. MS1 and MS2 are pod1 and are configured with replication (dsync) and host users 0-500. MS3 and MS4 are pod2 and are configured with replication between them and host users 501-1000. Ideally the active connections in pod1 would be split 50/50 between MS1 and MS2. When maintenance is performed obviously all active co...
