Depends on the purpose of the name(s). If you run everything on a single host, then mail.example.com. If you need to distinguish mail routing from other tasks (e.g. when running a spam filter on a different host and you want to tell other smtp servers to deliver to that instead of directly to your main mail server), then mx.example.com (or mx1.example.com) for that. Similar for other names: Use protocol or other special name to emphasize that service, otherwise it is more confusing than helping. - Jonas -- * Jonas Smedegaard - idealist & Internet-arkitekt * Tlf.: +45 40843136 Website: http://dr.jones.dk/ [x] quote me freely [ ] ask before reusing [ ] keep private
