Hi All
I have a dovecot cluster with directror and two IMAP Servers behind.
Since they are in geographical different locations I would like to have users to go to a specific IMAP backend server (if both are up) and only switch to the other if one goes down (failover).
As to my current knowledge the PassDB extra field „host=„ is not suitable in this case as it would never route the client to a different backend, even if the „user specific backend“ would be down.
Is their a way in dovecot to achive this? As far as I searched the documentation I could not find any information on this so far.
If not, it may also help if I could get certain users to „initially" go to a specific backend (since director usually routes a client/user to the same backend server it initially connects) and therefore it would be interesting to know how dovecot director chooses wether a user goes to server1 or server2? And if a client already gets to server2, how to bring it „back“ to server1?
thanks in advance, Steven
