Blocked senders list from Outlook app not recognized???

It's another political season and I am getting hammered with emails from every Tom, **bleep** and Harry running for office and his brother-in-law.

I use Outlook as my desktop email app and for months I have been religiously adding all these email sender domains to my Outlook Blocked Senders List. This seems to have had no effect, so I started doing some investigation.

I went to my online Cox Email and looked at the Blocked Senders List on Cox. NADA. Nothing. Not one blocked email listed! This seems to be a major weakness in the Cox online email setup, but putting that matter aside for the moment is there any way to add a list of blocked email addresses to the Cox blocked senders list?

There are hundreds of blocked senders in my Outlook email app and it is easy to export a text file containing this list, but adding all these addresses one-by-one to the online Cox email account is far beyond my patience.

Thanks.
