Re: Director to keep redirecting users to the same server even it is down

      There is nothing in director itself that sets backends up or down, you need to use something like poolmon to do this.

Hello,
why the director always proxying IMAP connections to the same backend even if it is down?
Also the director is showing the node as up although I have stopped the dovecot service on it:
doveadm director status
mail server ip tag vhosts state state changed users
Node1                  100    up    -             2
Node2                  100    up    -             3
on the director here is:
