MX 10 newsinc.net. This would cause mail for account@lists.jsa.org to be sent to newsinc.net, which you say is the new mail server. It also sounds like you've already tried something like this, and received the mail loop error. This indicates that the mail server hasn't been configured to accept mail for that domain; when it receives such mail, it looks for the responsible mail server (according to the DNS), sees itself, and calls for help. Lastly, to use the name lists.jsa.org as an SMTP host, you'd need the following record: lists.jsa.org. A 209.249.83.182 You can't use a CNAME record that points to newsinc.net, because you already have an MX record by that name (lists.jsa.org). A CNAME can't coexist with any other record of the same name. If you didn't have the MX record, you could use the CNAME record. Of course, once you have the A record, the MX record becomes somewhat superfluous, but it doesn't hurt anything. You could change it to this, though: lists.jsa.org. MX 10 lists.jsa.org. Hope this helps. ____________________________________________________________________ Chris Buxton cbuxton@menandmice.com Men & Mice http://www.menandmice.com Makers of: QuickDNS Pro
