Now that you mention it, I've seen few in the past few days with no MX 
records for the sending domain, even with a PTR record for the sending 
host.  Not the same, but similarly strange and recent.

I'd be happy to add a SpamAssassin or postfix rule to ignore mail from 
senders with no reachable MX for a reply.

All that said, somebody might have just messed up their BIND views.
