Cant seem to get whitelist right... what am I doing wrong?

I want to get every email from a particular domain:    buffnews.com

I added .buffnews.com and *@buffnews.com to the global whitelist.

BUT then this email address was placed into my quarantine email <email@email.buffnews.com.com> Any idea why and how can I change setting to allow these emails through?

I  had guessed they are bulk emails and turned off quarantining them in my policy but then got a ton of email from other sites I did not want so I turned quarantining of bulk emails back on.

Any ideas?
