Hello,
I'm still using a foundry ServerIron XL to do some load balancing between
our mail servers.
When both my servers are up on running (on all load balanced ports) the
ServerIron nicely balances the load between the 2 servers. However, I've
noticed today, while I took on of the 2 servers down for maintenance, that
the ServerIron is not taking the unresponsive server out of the chain.
Therefore, my customers where now getting timeouts since their traffic was
being directed by the foundry to the unresponsive server.
I don't see the problem with my config, but obviously there is something
missing.
Here is my config:
Current configuration:

What am I missing?
