I have started to get a large amount of spam even though I have a current and updated version of Zone Alarm. I set the challenge filter to highest and took everyone out of my allowed. But when I do a test email to myself from a hotmail account I have it just allows it through to the inbox and the challenge email does not go out but says that it cannot go because one of the recipients "m" wont allow. ??? What is happening?
Thanks for any help.

Operating System:Windows XP Home Edition
Software Version:
Product Name:ZoneAlarm Internet Security Suite
