I'm a little confused. Can somebody summarize this? Is it that a mail server inside cox or rr is likely to get marked as spam because it has an ip that is classified as within those providers' "residential" ip-space?, or does it relate to reverse lookup verification of the sending mail server? or both? Or what??? :-\
If you look at the header of my original post, you'll see that the originating IP of my laptop is 68.7.51.89. That is the IP allocated to my cable modem by Cox, and is within the 67.7.0.0/16 netblock.
ANY server I use (unless it is re-writing headers) will have that IP somewhere in the mail header. A thorough spam filter will check all IPs in the header, and if that filter happens to be using the Spamhaus PBL, then it will block the e-mail.
I submitted a request to have the IP removed. I also called Cox and had my complaint escalated to someone that knew what they were doing. Hopefully within the next few hours (if not already) it's been resolved.
