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 firstname.lastname@example.org 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 still get tons of Spam on my old email address on a family member's account, but I have noticed the new usernames I created on my personal account gets NO spam. For those not attached to their specific username, I would suggest creating a new email address, or even several, and comparing which get SPAM. I wish Cox would just fix the problem, but that seems to be taking a long time.
