dyndns MX record not found

noir911 · 02-14-2007, 05:04 AM

If I add MX to dyndns it gives error -

The MX entered ("mail.domain.dyndns.org") did not resolve or resolved to a CNAME.

My wildcard is enabled. I also tried enabling "Backup MX" in dyndns.

Here's my BIND domain.dyndns.org file

;; name servers

domain.dyndns.org IN MX 5 mail.domain.dyndns.org.

;; addresses for the canonical names

localhost IN A 127.0.0.1

;; aliases for this box
www IN CNAME domain.dyndns.org.
mail IN CNAME domain.dyndns.org.

nslookup resolves nicely for <anything>.domain.dyndns.org.

I've had this happen to me, too. I found that if you try to set up MX records *immediately* after you have set up the CNAME, this problem seems to happen, because the CNAME has not percolated through the system. You are working on a DNS system which is a long way removed from the Web Browser you are entering data from, so give some slack!

Give it a while and try again...though reading your post again, if nslookup resolves, the above may be a total load of rubbish

Here is a copy of one of my working zone files that I posted in a fedora thread a few days ago , this is the way a zone file should look.

Question : why have you got your local host 127.0.0.1 in your zone file ???? , it is not suppose to be in there.

Code:

NOTE : The inclusion of the dots "." after each of the .com  enties !!!!!!
        DNS is very particular about the dot entries.

MX records must not point to CNAMES. You may only use an A record in an MX record. Whether your DNS host allows you to point an MX record to a CNAME isn't the point. The point is you're not supposed to do it.
