said by Ellen098:What's interesting though is that the IP addresses for the servers were the same, although they were different form what you got:
SERVER: 208.67.222.222#53(208.67.222.222)
Since the IP addresses are the same, I assume that means that my changing the outgoing server name shouldn't make a difference. Also, it's surprising that the IP you got for mchsi.com was completely different from from the one I got. Don't mail servers have static IPs?
I was puzzled by this comment. 208.67.222.222 is not even an mchsi IP address, much less a mail server address. The IP address in my printout is an RFC 1918 reserved IP address for private networks; it is my residential gateway (a Pace 4111N ADSL2+ modem with a router section). The IP address in your printout is the primary DNS server for OpenDNS. These are the respective DNS servers queried by our 'dig' commands!
The 'nslookup' command tells me that the servers are different:
C:\Dig>nslookup mail.mchsi.com
Server: homeportal
Address: 192.168.42.1
Non-authoritative answer:
Name: mail.mchsi.com
Address: 97.64.187.44
And then:
C:\Dig>nslookup mail.mediacombb.net
Server: homeportal
Address: 192.168.42.1
Non-authoritative answer:
Name: mail.mediacombb.net
Address: 97.64.187.40
BTW, the semi-colons are comment delimiters.
The "Question" section in my results recapitulates the question: "What is the name of the MX server for the 'mchsi.com' domain?"
The "Answer" section displays that server name.
The "Authority" section displays the authoritative name servers for the 'mchsi.com' domain.
The commented servers at the end are the recursive name servers used by the 'dig' command.
