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. ie in main.cf: smtpd_client_restrictions = permit_mynetworks .... check_client_access hash:/etc/postfix/spamsources mtpd_sender_restrictions = permit_mynetworks .... check_sender_access hash:/etc/postfix/spamsources and in /etc/postfix/spamsources: xyz 500 This TLD sends spam - get lost.
