I posted a couple days ago about having two domain names going to one exchange server. I beleive i have setup everything setup correctly but when people try to send to this second domain name they receive the relaying denied error. The only thing I am unsure of is where the second mx record should point to? My two domain names are hartadvisers.com and hartadvisors.com. We've been running fine with hartadvisers.com. Where should hartadvisors mx record point to?
