Search Again: MX and CNAMES revisited, listservs From: billc@greenbuilder.com Date: Tuesday, April 18, 2000 Time: 10:00:14 pm Hi folks, A month or so ago I learned that MX records shouldn't be CNAMEd. So I went through and changed all my records. Now I'm wondering about my listservs. Part of the reason I'm wondering about it is that I want to set up a secondary mailserver to hold mail in the event my listserv machine goes down, and deliver it once it comes back up. I have a similar setup for my mailserver, and would like to use the same mailserver as the secondary list machine. If the relevant part of my setup is: greenbuilder.com. MX 10 mail.greenbuilder.com. greenbuilder.com. MX 20 mail2.greenbuilder.com. mail.greenbuilder.com. A 216.171.28.121 mail2.greenbuilder.com. A 216.171.28.3 lists.greenbuilder.com. A 216.171.28.120 where mail2 is the backup for mail1, can the listserv just get a second line that says: lists.greenbuilder.com. A 216.171.28.3 with the appropriate settings in the mail2 server to hold and send? Should lists.greenbuilder.com be treated as an MX, since it is essentially a mail server? What about the CNAMES that point to lists.greenbuilder.com - they appear to be working just fine, but then again I had not seen any problems with the CNAMEd MX records either... I once thought I knew what I was doing. Now I'm not so sure. ;-/ BC Bill Christensen billc@greenbuilder.com Green Homes For Sale/Lease: http://www.greenbuilder.com/realestate/ Green Building Pro Directory: http://www.greenbuilder.com/directory/ Sustainable Bldg Calendar: http://www.greenbuilder.com/calendar/ Sustainable Bldg Bookstore: http://www.greenbuilder.com/bookstore
