NS Lookup does not find MX record
My client created a domain on Whois.com and asked me to set up the email. I created an A record (mail.mydomain.com) pointing to an exchange server on our domain. I then created an MX record for .mydomain.com pointing to the new A record. We waited 24 hours. The mail did not flow all mails were bounced tjat were addressed to Jane@mydomain.com.
I did an nslookup on the MX record:
c:\nslookup
Default Server: ServerName.comcast.net
Address: xx.xx.xx.xxx:53
>Set type=MX
>mydomain.com
Server: ServerName.comcast.net
Address: xx.xx.xx.xxx:53
<root>
primary name server = root
responsible mail addr = abuse.opticaljungle.com
serial = xxxxxxxxxxxx
refresh =28800
retry = xxxxx
expire = xxxxxxxxx
default TTL =1
>
All other mx records I enter for exchange servers I have set up return:
Server: Comcast server name
address: IP address:53
Non-authoritative answer:
domain.com MX preference =10, mail exchanger = domain.com
Any ideas why this mx record is not working?

Ok, I guess we can wait and see, but I have set up many MX records and they usually work within 24 hours. You may be right though. I subsequently noticed that Whois.com is Singapore based, so there may be a larger delay than using Network Solutions and having the record propagate in the US only which is where all my client's email comes from. Thanks, I will let you know if waiting works

@sarotsab: You mean email flows over A record and all those blogs / MS documentation talking about MX record are baseless ????
I have seen cases where MX record starts working after 96hrs even, however industry standards state 72hrs is appropriate.
