I am using Magic Mail Monitor and have been using CPF v2.4 with no problems. I use magic mail to see what’s on the server and delete emails that I don’t want to download before opening Outlook Express. Decided to upgrade to CIS 3.5. I did a clean install after uninstalling CPF 2.4 and cleaning the registry. I did this three separate times and each time installed CIS at each of its levels of protection from just the firewall to Defense+. With uninstalls and registry cleaning in between. And each time adding Magic mail to be trusted application. No matter what, I can not get Magic Mail to delete emails from the ISPs server. When I uninstall CIS, back to normal. Currently back to 2.4. Any insight would be appreciated. Thanks.
