It's heartwarming to a greying geek that a 5000+ words retrospective on greytrapping is turning out to be popular - https://nxdomain.no/~peter/eighteen_years_of_greytrapping.html (tracked https://bsdly.blogspot.com/2025/08/eighteen-years-of-greytrapping-is.html)

It's now been a week since my population of spamtraps rolled past the number of inhabitants in my home country of Norway. Here is the retrospective:

Friends, it finally happened. On August 7th, 2025, the number of spamtraps intended to fool spammers rolled past the number of inhabitants in my home country of Norway. It's time for a retrospective.

Following up on previous, the LinkedIn discussion revealed that there are people who have not heard about greylisting.
So here is my 2012 piece with updates, "In The Name Of Sane Email: Setting Up OpenBSD's spamd(8) With Secondary MXes In Play - A Full Recipe" https://nxdomain.no/~peter/in_the_name_of_sane_email.html

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)
