Multi outgoing Listeners

[Oscar Cardiel]

Hi,

I have configured two listeners (different IPs but in the same subnet and applied in the same data port) with the finality to have a primary listener and a secondary listener in case the primary will be added as blacklist. Is it possible to configure priorities between both listener to choose to primary and secondary one or the solution is to suspend the second Listener? Actually both listeners are working doing a round robin with the outgoing traffic.

Yes, you usually do this via DNS with weights on your MX records. (assuming they are incoming listeners).

Hi Ken,

yes, you are right for incoming listeners but in my case is for outgoing. any suggestion?

thank you in advance for your help.

You want to define which listener it will go out via?

I think its going to use the lower IP... but I'm not sure.
