When I have Zone Alarm engaged, I receive an error message when my e-mail program, Eudora (, automatically checks for e-mail messages at regular intervals. However, when I manually check for messages, messages are delivered without any difficulty. When Zone Alarm is not engaged, the automatic checks of my e-mail messages at regular intervals produces the messages without any problems. Would any of my settings on Zone Alarm affect this, and if so, how would I modify the setting to allow the automatic check to work properly?

Operating System:Windows XP Home Edition
Product Name:ZoneAlarm Anti-Spyware
Software Version:6.1
