Much of the spam has the new TLDs on it.  By filtering those, I can 
eliminate it and make my people happy.

I don't have a lot of spare time.  I have another job to do.  If I find 
myself idle in the future maybe I'll revisit the issue.

It's not my job to punish, I'm just filtering out crap.  The new TLDs 
send us only crap.

Yes, two.  They eliminate a good chunk of spam.  Filtering the new TLDs 
will get rid of much of the rest, although some do use .com.  They will 
get the following message:

So, I'm providing a clear message to those whose emails are declined.
