problem - mail to/from isc.org thought of as spam

[Robert Cates]

Hi all,

I have exim 4.54 running with spamassassin 3.0.4, and I have my 
user_prefs set with 'whitelist_from   *@isc.org' and 'whitelist_to   
*@isc.org' but all mail to/from the mailing list gets put in my spam 
folder.  Does any body have an idea why?  I'm a member of several 
mailing lists, but this one is the only one that ends up in my spam folder.

All help will be greatly appreciated!
Thanks, Robert
