[exim] round robin -> load balancing query

Hi

I have a fair amount of users hamering my internal smtp server / and also would be great for redundancy.

I would like to know.

Would it be ok to just add another machine and then to just update the DNS to handle the round robin
effect.

So in short, if i dig smtp.internalmydomain.local it would return two ipaddresses.

Just something i was thinking.
