Hi all,
Recently I noticed this in my logfile:
0.3.9.0.0.0.0.0.0.0.0.0.0.0.0.0.0.2.0.0.4.6.8.4.0.b.8.f.7.0.6.2.bl.spamcop.net:
Host or domain name not found. Name service error for
name=0.3.9.0.0.0.0.0.0.0.0.0.0.0.0.0.0.2.0.0.4.6.8.4.0.b.8.f.7.0.6.2.bl.spamcop.net
type=A: Host not found, try again
According to Postfix/postscreen it happens to be the reversed notation
of the IPv6 sender of the email:
May 11 23:14:27 terra postfix/postscreen[4111]: PASS NEW
[2607:f8b0:4864:20::930]:43019
Can someone explain why bl.spamcop.net reverses the ipv6 ip, thus not
recognizing it like postscreen?
Thanks, Jos
