In our environment, we have a small cluster of incoming mail servers, each running Postfix & MailScanner. We balance these via DNS, in the same way that Google, Yahoo, and many other email players do: our MX points to a single hostname (mail01), which in turn has A-records for each of the machines in the cluster.
ubisoft.com. 300 IN MX 10 mail01.ubisoft.com.
mail01.ubisoft.com. 3600 IN A 188.8.131.52
mail01.ubisoft.com. 3600 IN A 184.108.40.206
mail01.ubisoft.com. 3600 IN A 220.127.116.11
Done and done - it works like a charm, and it is fantastically easy to set up and maintain.
