This is to summarize...
If no MX is found for your domain, the MTA will sent the mail to the 
resolving host.

$ host -t MX infoservices.in
infoservices.in has no MX record
$ host infoservices.in
infoservices.in has address 85.199.129.73

So, your mail to user at infoservices.in will be delivered to "user" at 
85.199.129.73.

Cheers.
