Newbie question - bulk upload of white and black lists?

Hi there
I just setup my e-mail account and I have a long list of whitelist entries that I’d like to upload. I am currently using the control panel managed version of SpamAssassin. Is there a way to bulk upload entries? The only thing I could find is to read all entries in the address book. That doesn’t appear (again, I just started this) to have facilities for specifying @domain syntax. Maybe I didn’t understand it?
Thanks and apologies if this is post is in the wrong place.
