The thing is, the IP that SA checks is the one in the "Return-Path" header: <taxqlnsu at as14.nwbl1.wi.core.com>. The absurd thing is that it is not in fact a dynamic address:
cer@nimrodel:~> host as14.nwbl1.wi.core.com as14.nwbl1.wi.core.com has address 169.207.80.56 cer@nimrodel:~> host 169.207.80.56 56.80.207.169.in-addr.arpa domain name pointer as14.nwbl1.wi.core.com.
It has correct reverse DNS, can't be dynamic. But dnsbl.sorbs.net says it is.
Why not? I _know_ that I'm on a dynamic address, and yet... igloo:~ # host -a 209.6.158.239 Trying "239.158.6.209.in-addr.arpa" ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 3109 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;239.158.6.209.in-addr.arpa.
