• PTR record not valid for all domains

  - by charnley

  We have an issue sending emails to certain domains, namely Time Warner and Cox. Last week, we decommissioned our Exchange 2003 server and now our Exchange 2010 server is doing all of the transport for our domain. We run our own authoritative name servers, so we are in charge of the DNS and have modified our PTR record to reflect the new server.…

• How to secure a group of Amazon EC2 instances

  - by ks78

  I have several Amazon EC2 instances running Ubuntu 10.04 and I've recently started using Amazon's Route 53 as my DNS. The purpose of doing that was to allow the instances to refer to each other by name rather than private IP (which can change). I've pointed my domain name (via GoDaddy) to Amazon's name servers, allowing me to access my…
