I touched on this recently but in a different context, that being multiple postfix instances on one box all used as an outbound relay farm. You wan to use round robin DNS for this. What you want to accomplish is very simple. Create a DNS CNAME entry of something like relay-farm.your-domain.tld and point it to something like tractor.your-domain.tld. Then create an A record for each SMTP relay box's IP, with all of these A records having the name tractor.your-domain.tld. This should enable round robin DNS. Now, simply add this to main.cf: relayhost = relay-farm.your-domain.tld I think this is right. If not it's darn close. -- Stan
