I would recommend using the "graylist-exception-rdns-file" option 
instead of whitelisting those servers, because whitelisting will allow 
them to bypass all filters, including sender/recipient blacklists.  You 
are correct about the domain wildcard however -- you'll have to list all 
of Yahoo's TLDs individually.
