The MX records for expofreight.com are as follows:

expofreight.com mail is handled by 30 dmss2.webindia.com.
expofreight.com mail is handled by 10 61.16.173.99.
Isn't this a violation of RFC 1035?
Yes
Shouldn't SPF check on this MX record result in NXDOMAIN?
I would say the the ip address in MX record should be ignored, so only
dmss.2.webindia.com would be result of such MX lookup. Putting warning
in the logs about the ignored mx entry may also be appropriate.
