Hi,
Stan: My question is not how I setup the solution, but how I *BEST* (best
practice) setup the loadshared/failover postfix solution I described
earlier.
I dunno if there is a BCP covering smtp submission/relay server load
balancing/fail over. I'd make an educated guess that just about
everyone with more than one submission/relay server is using round robin
DNS.
*raises hand*
We're using Linux Virtual Servers for load-balancing all public-facing
bits (and a handful of internal bits) of our entire mail cluster.
Once you beat the ARP configuration into shape to prevent a random real
server from taking over the load-balanced IP it seems to work well.
We found that DNS-based round-robin strategies didn't actually balance
the load very well.
