I have Trend Micro SMB for my email anti-spam. What I have been doing is compiling a blocked senders list of spam that has gotten through the normal filters. I have a list of 100+ domains that send spam.
My question is this, is there a place where people share their black lists? Is there somewhere I can go to get a list of known bad domains, that I can just put in a text file and import it into Trend Micro, help cut down some of the work.
I know that there are black lists that you can put in IP's for but I was looking for an actual list.
Let me know what other admins have had good luck with.
