oursite.net has no MX record
After we upgrading from Domino to Exchange 2007, the MX record in DNS to the new server was overlooked until today. The MX record was deleted for the old server and a new one added for the new server to the DNS. We are concerned as "there is not parent MX folder" (our AD admin reference). He tried force replicating and that did not resolve.
commands:
> host -t mx oursite.net
oursite.net mail is handled by 10 oldsername.oursite.net
>
# our AD admin made change in the DNS
> host -t mx oursite.net
oursite.net has no MX record
(tried flushing nslookup, same result)
Anyone experience this or know the solution?
Thank you,

I may be going about this the wrong way, so if I am, just ignore me. There is a 24-48 hour delay for external DNS records to update, so it may take some time for the change to process depending on the DNS server you hit in your query. How long ago did you make the change?
To be quite honest I would not be concerned about this. an MX record as it is used for mail delvery, is primarily used for external resolution or server to server comms. Internally your email client and server ie exchange and outlook will find each other via a records. as long as you have an a record for the new exchange server then you should not have any problems.

thanks for the replies guys !
The record was changed on the internal DNS so the change should be instantaneous. Our external MX records are good.
The concern is for our internal *NIX server and IBM i ( as/400) servers.
Are we just being too paranoid ?

Maybe and maybe not. If the AS 400's are end mail by domainlookup via an smtp service then no you are not. If it is sending mail via being told a DNS/IP name then yes you are. If the case is the latter then the server will know its mail server and will communicate via what ever port is configured (25 of course is the standard) and the mail server is going to listen on that port. Hope this helps
