I can't get access to kernel sauce right now, but I'm hitting over 1,000 entries from woodpeckers[*] etc; is there some upper limit, or is it just purely dynamic? aneurin% freebsd-version 10.4-RELEASE-p9 [*] A fairly loose definition in the anti-spammer community, but it includes attempts every few *seconds* when they encounter my RFC-compliant banner, when I make 'em wait a bit for my 220, and those who regard 5xx as a challenge. Perhaps I should consider an external firewall; at the moment the (consumer-grade) router allows only certain services to certain servers (and doesn't bother logging the rejects, much to my disgust) and its "IP blocking" simply doesn't work, so the mail server blocks the spammer IPs instead (entire countries where necessary). -- Dave, who has been accused of being an "anti-spam nazi"
