Spam Filter

There is a lot of spam coming in from say Pandora Store or Moncler Outlet and others. Their name is mentioned as part of the address, in “quotation marks”, but the actual is something else each time. Filtering that is useless. No names or anything “filterable” mentioned in the body. Tried to make a filter for the above “name”, but was unsuccessful.
How to formulate a filter that can catch, e. g. “Pandora” as part of the email address?
