BTW if you request a ACM cert for &lt;domain&gt;, make sure you set up one of the admin@, administrator@, hostmaster@, postmaster@, webmaster@ email addresses for &lt;domain&gt;, as the ACM verification email is sent to these addresses, in addition to the WHOIS registered for &lt;domain&gt;.<p>The ACM certs cannot be used with an EC2 hosted site.
