Ten years plus on "Effective Spam and Malware Countermeasures - Network Noise Reduction Using Free Tools" https://nxdomain.no/~peter/effective_spam_and_malware_countermeasures.html still seems to be relevant (mod that we never got #IPv6 greylisting done) #malware #networksecurity #antispam #OpenBSD #internetsecurity, #networking #mailsecurity #packetfilter #countermeasures #networkmail #PF #greylisting #spam #FreeBSD

The 2014 article "Effective Spam and Malware Countermeasures - Network Noise Reduction Using Free Tools" has been liberated as https://nxdomain.no/~peter/effective_spam_and_malware_countermeasures.html - previsously only available tracked as https://bsdly.blogspot.com/2014/02/effective-spam-and-malware.html.

Likely still useful if you follow keywords like #malware #networksecurity #antispam #OpenBSD #internetsecurity, #networking #mailsecurity #packetfilter #countermeasures #networkmail #PF #greylisting #spam #FreeBSD (and now all #tracked links to my stuff have an untracked equivalent)
