Search Again: Re: advice From: Men & Mice Support Date: Tuesday, January 8, 2002 Time: 5:00:57 am Here's the official story, as I understand it: - According to the relevant RFC, an MX record is not necessary in this case. Other mail servers should, in the absence of any MX record, act as if there were an implied MX record that looks like this: lists.digitalfrontier.com. MX 0 lists.digitalfrontier.com. - However, at least some mail servers don't do this exactly. The behavior I've seen (from EIMS) is, mail delivery is attempted only once this way. If delivery fails, the message is not queued for later retry. This is probably because, in the majority of these cases (where the domain name in the email address is a zone name), the A record points to a web server, which often has no mail service running on it. ____________________________________________________________________ Chris Buxton Men & Mice support@menandmice.com Making DNS Easy At 3:20 PM -0500 1/7/02, Karl Schroll wrote: >domain in question: digitalfrontier.com > >Name server is ns1.digitalfrontier.com. > >I have an A record for lists.digitalfrontier.com pointing to the IP address >of a machine that is a list server.
