My ISP (Qwest) uses the commercial version of hotmail as their mail service for subscribers. In over a year, I don't remember seeing a single spam email. I suspect Tim's argument is the reason. Hotmail is *known* for spam, so they would get lots of practice at recognizing it and removing it, and thus become very skilled at it. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
