I get at least 20-30 spam emails delivered through Cox mail servers even though my spam settings are set to high. Funny that my desktop McAfee app places most of them in my Outlook spam folder. If McAfee can identify them why not Cox mail servers with maximum spam settings? I send them daily to email@example.com but I believe this to be a waste of time because the junk keeps delivering....Also should be noted that some legitimate emails do not make it through their servers and I have to use gmail accounts to get them delivered.
I am having the same problem and it appears it has something to do with Cox outsourcing their email servers...though, there have been no permanent solutions provided so far. Prior to this I NEVER received a single spam email in my inbox. Not happy.
