blocking mail from subdomains of in.net

Lately my server is getting hammered by spam from addresses from subdomains of domain "in.net"; for example:
 
dumarram.in.net
chinambe.in.net
nve9.in.net
urd9.in.net
cleonsigion.in.net
hophember.in.net
kpd8.in.net
df7t.in.net
ameryucke.in.net
nd3b.in.net
hourenry.in.net
 
I use the IPNetInfo program to determine IP addresses for these domains: http://nirsoft.net/utils/ipnetinfo.html
 
And I get some useful information. The trouble is, the spammer is using many different subdomains.
 
Is there any easy way I can block all incoming mail from all subdomains of in.net? I'm getting really tired of these in.net guys.
 
Thanks as always for your advice.
 
Eric

I just noticed this same issue. I'm running SmarterMail Enterprise 14.2

Emails that are sent from within the system to me@hidden.mydomain.com that is an external domain are instead being delivered locally to me@mydomain.com
