Exchange 2016 anti spam

I am using the built in Exchange 2016 anti malware filter. I've been trying to use this command to except email from an email address. But its not working

Set-ContentFilterConfig -BypassedSenders sender@domain.com

The emails for the address I put in are still getting blocked by content filter.

is there something I can run to make sure the email address is being bypassed? Either way, if it is, its not working.

please help. the only way i can get emails through is to turn off the anti malware filter, but i get flooded with so much rubbish,
