I just recently installed Zone Alarm Internet Security Suite 2009 3 onto my computer. I use Windows XP Home, and my email program is Outlook Express 6. I have a frequent problem with the connection between OE and the host server for my ISP, which is Integrity Online. I get an error message that the "host 'pop.integrity.com' could not be found". The settings for my POP 3 email service are correct. Usually when I go to the "tools" menu of OE and click the "send/receive" link, my waiting mail is delivered to my inbox. What could be causing this problem? And how do I fix it? Any help with the elimination of this problem will be appreciated.

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