I received a bounce message stating my IP was listed at Spamhaus. I

Ref: PBL031205
68.7.0.0/16 is listed on the Policy Block List (PBL)
The entire Cox IP block is listed.
Great.
Even using my own mail server, my Cox supplied IP will still appear in
the header (unless I use web mail, which my server does support, but I
don't like using web mail).

Cox blocks outbound ipv4 port 25 from their network anyway. Do you have
business class service?
Most big cable and dsl providers disallow outbound on smtp nowdays due
to spambots.
Lots of places are dropping email that doesn't reverse dns to a valid
mailserver. Make sure if you are on cox business that they give you
reverse dns.
