Monitoring of director back end nodes

[Dan Conway]

Hello,

When working with director, the state of the backend nodes are not 
checked by Dovecot. The state always remains as "up". I understand that 
there are external applications documented that monitor backend nodes, 
and changes the state of them to "down" if they become unresponsive. The 
question I have is are there plans to implement something built into 
Dovecot that would monitor and change states based on backend "health"? 
Or will it always be dependent on an external service?


Thanks.
