Cox Webmail Blocked Senders List / Exception List - No way to modify

I've noticed recently that emails from several legitimate accounts are ending up in my spam folder. I had previously had the email domains (e.g. Yahoo.com) in the blocked senders list, then added the specific email accounts (e.g. <>@Yahoo.com) in the exception list and their emails used to be delivered to my inbox as desired. This was working great until recently. I went on the Cox webmail site to check to make sure my blocked senders and exceptions were still entered correctly. But it looks like the Cox webmail settings page has been changed. There is no way to add/modify Blocked Senders, and I no longer see an exception list. I'm using IE11, but have also tried Chrome and Firefox browsers just to check if this was a browser issue, and do not see a way to update/add the blocked senders and exception list. Has Cox removed the blocked senders/exception list? If not, how do I update? Appreciate any help here. Thanks.
