e-mail deliverability
I had a bounce today from a customer and this was the message text:

I checked SenderScore of my cox ip and it got a 20 which is really really bad. When I checked my score of our actual vps that does the e-mailing, it has a 97. My assumption here is that it is cox that is giving me problem but which one of these are effecting me? Is it because I am on cox's shared pool? Any suggestions on how to enhance deliverability? No spam, just sending customers reports...
Thanks!

IP Reputation Class Volume: Transitory
Risk: 40% The final reputation classifications that can be used in making decisions about the IP.
Volume 0 Calculated daily average of the volume from the last 30 days, ranging from 0 to 10 with 0 being a source IP having no monitored traffic.
Weighted Risk 61% This value represents the risk level, a composite value that weights a host of variables. A value of 0 in the Risk Level represents a reserved IP and a value 100 represents a blacklisted IP.
Spam Ratio 0% The spam ratio is calculated by dividing the monitored spam volume by the total monitored volume over the last 30 days.
Valid Bulk Ratio 0% The valid bulk ratio is calculated by dividing the monitored valid bulk volume by the total monitored volume over the last 30 days
That's the report it gives me back for my mail gateway. So it isn't my cox ip that is causing the problem? because when I lookup my cox IP I get this:
