if you run exim4 and live spamassassin mta-time the teergrube config is a lot of fun (teergrube: german for tarpit). unfortunately, running mta-time spamassassin takes a MENTAL amount of server-side resources esp. if you enable clamav, pyzor and razor like i used to. after a couple years i went "this is nuts" and left greylistd running but did forwarding-only. btw the other one to watch out for is the Iranian attack against OpenVPN. i had repeated attempts to break in on OpenVPN come up and had to add that to recidive as well, with some custom pattern matching. a week later the slashdot announcement came up, "Iran sponsored hackers break in to somethingorother by turning OpenVPN servers into botnets". keeping an eye on your fail2ban logs you get a fairly good advance indication of massive govt sponsored hacking attempts. l. -- --- crowd-funded eco-conscious hardware: https://www.crowdsupply.com/eoma68
