I am having the same problem with Cox Webmail marking legitimate email as Spam. The problem started a few months ago when I noticed I hadn't received bills that are normally sent to me every month.
I seldom log into Cox Webmail because I download my email to Outlook on my desktop. When I finally logged into Cox Webmail I saw that Cox had moved these emails, along with many other legitimate ones, to Spam. I marked these emails as "Not Spam" and moved them to the Inbox. However, Cox seemed to ignore this because the next month, the bills were once again marked as Spam. I have tried defining the senders as Contacts and using the Webmail filters but all of that seems to be ignored.
This is going to be a serious problem for anyone who is having Cox Webmail marking the emailed bills as Spam. Either fix the problem or provide an option in Webmail for the user to turn off the Spam filter!!!
