Thanks all, for your support.
I did fed spammy emails, most are blocked but users still get bunch of those emails a day. I added this in MTA:

smtpd_sender_restrictions  
<http://www.postfix.org/postconf.5.html#smtpd_sender_restrictions>  
=reject_unknown_sender_domain  
<http://www.postfix.org/postconf.5.html#reject_unknown_sender_domain>

in the .cf file I addes
blacklist_from *.review
blacklist_from *.work
blacklist_from *.date

I will be monitoring,

Thanks,

 Can I configure Spam-assassin to drop emails with extensions .review?

 From: "Patio Deals" <PatioDeals@recolong.review>

untested:

 header  FROM_TLD_REVIEW   From:addr =~ /\.review$/i

Also, if you want to poison-pill such senders, do it at the MTA level.
