Tell ya what. Let's hold the suggestions here. This one looks like something I
can handle. (I really need things spelled out.)
BTW, the SpamAssassin enlist trick caught about 20% of this flavor of spam. But
I'm really OK will killing the TLD.
I did some googling on this and some claim Baracuda has this spam style licked,
but I don't find that to be the case. I do have Baracuda as my first RBL.
I didn't mention it but the odd thing is this .stream spam goes to one email
account. Perhaps in a daze I clicked unsubscribe.
Thanks all for the suggestions.

Put the offending TLD in a map and have that map referenced through
check_sender_access and/or check_client_access.
smtpd_client_restrictions = permit_mynetworks
mtpd_sender_restrictions = permit_mynetworks
and in /etc/postfix/spamsources:
xyz 500 This TLD sends spam - get lost.
