Blocklists - IP, DNS, RBL and ads - Which do you use?
I was going over some CSF settings that had some blocklists configured, and it prompted me to take a look at all of the blocklists I've been using over the years.
Which blocklists (or whitelists!) would you recommend?
For your, firewalls, DNS servers, Mail servers, Ad Blockers, AV definitions/signatures, etc...
Something I use on my mail server:
I like your approach @stoned !
None. It's foolish to delegate your filtering to someone else.
Go on then, how are you doing your filtering?
Community maintained efforts are better than solo efforts. A collective database contributed to by many is a good idea in many cases, but not every case.
Somehow magically deleted this line while pasting earlir,
sort -u /tmp/iplist.txt | grep -iv no | grep -v ':'> /tmp/exim.txtwithout which the script doesn't make sense.
I do similar custom filtering on all services just like this one, as well as general known bad actors from multiple reported bad actor lists.
