That's what we do, and the machines are generally reliable enough for our purposes. However because we depend on the DNS to spread the load, a failure is quite visible to users. This is the main cause of trouble; we almost never lose data from failure of a mail queueing machine because they are RAIDed etc. Some kind of lower-level load balancing (LVS, BigIP, etc.) can fix the failure-visibility problem but that does not imply you have to make the whole system tightly coupled.
