Hi,
I have 3 smtp servers 10.0.0.2, 10.0.0.3, 10.0.0.4 under a cluster with the 
load balancing done by 10.0.0.1. The pf rule on 10.0.0.1 is

ext_if="fxp0"
internal_smtp_servers="{ 10.0.0.2, 10.0.0.3, 10.0.0.4 }"
rdr on $ext_if proto tcp from any to any port 25 -> $internal_smtp_servers 
round-robin sticky-address

If 10.0.0.4 port 25 goes down, how do I force pf to remove 10.0.0.4 from its 
table.

Regards
Sunil Sunder Raj
