I have a simple two node Keepalived cluster for two HAProxy servers running in TCP mode for sending mail to postfix. When setting up HAProxy to send-proxy and get the client IP to forward to postfix. I get errors in postfix that is telling me the proxy format being received is not valid. Postfix is configured to accept the proxy format from HAProxy. I can get it to work without setting up a cluster and taking KA out of the configuration.
Is this a problem actually with Keepalive not providing valid information to forward through HAProxy or is a problem with HAProxy.
