That use of CNAMES by AWS ELB poses a problem for websites setup as
domainname.tld and also have MX records for the domain. I ran into this
problem recently with an organization that moved their website to AWS and
found they had to use the Amazon real servers' IP address in their DNS
instead of the ELB hostname. Unfortunately we were told the real server
doesn't have an IPv6 address. Only the load balancer does.
