Ο Jose-Marcio Martins da Cruz, συγγραφέας του j-chkmail, ανακοίνωσε τη δημιουργία μιας ακόμα DNSBL,της dnsbl.j-chkmail.org:
This list is constituted empirically, based on hostnames, which I identify as being residential lines (static, dynamic, dhcp, dul, ppp, …).
and:
dnsbl.j-chkmail.org is a list of IP addresses and mainly expressions matching hostnames clearly used by residential installations. j-chkmail uses this list not to block connections from these addresses but for setting limits (connection rates, messages per time window, …) down to normal limits needed by this class of addresses.
Όποιος θέλει να κρατάει τοπικά secondaries, μπορεί να του στείλει ένα email.
