pavlovmedia spammer ring

There is a spammer ring called pavlovmedia that pelts the mail server with spam from diverse locations consisting of small subnets.

I had been rejecting their traffic up to the point that they began multiple attempts to deliver rejected communications and ever wary of backscatter black listing because of email rejection policies I opted for drastic action.

The situation grew so bad for me with so many of these unsolicted business emails that I ran a filter on my logs and extracted their IPs from which I derived their various subnets.

These I submitted to the firewall and now all of those (many) packets are dropped. I kept thinking that the Spamhaus project might pick up on their activity but alas, my efforts were to no avail ...
 

I like to reject their email when I gain contempt for an entity. Others I simply instruct the server to discard. The transaction appears normal to the delivering server and I simply never see the traffic cluttering up my inbox.

It would appear that my contempt for pavlovmedia didn't sit too well with a number of their spammer cohort given the various multiple log entries for a single delivery.

Oh well, be that as it may the die has been cast. I have an automated process extracting the trouble children now so that I may eliminate the rejection backscatter sooner rather than later.

Spammer cockroaches beware !
